  • Fabrication of a Polyimide Film Pneumatic Actuator by Molding and Welding Processes

    The bellows pneumatic actuator, which is made by folding a non-stretch film, has been proposed for various applications because it is easy to fabricate and is extremely thin and light. However, it has subpar durability performance, especially in the folded part of the film. In this study, we propose an actuator with a pod structure that possesses high design flexibility and is free from folding. A method of molding a pod structure on a polyimide film was established and a pneumatic actuator was successfully fabricated by using PI films. Two types of PI film pneumatic actuators with the same curvature, bellows type, and pod type were fabricated. Both were confirmed to have equivalent output characteristics. The bending angle and generated torque of the pod-structure actuator were 34° and 3.3 mNm, respectively. In addition, the pod structure has approximately twice the durability of the bellows structure. By using the fabrication method proposed in this paper, it is possible to realize an air chamber (i.e., an actuator) that has both high durability and bending motion.

  • Concept and Prototype of Soft Actuator for Liquid Nitrogen Temperature Environments
    Daisuke Yamaguchi; Tatsuya Hanaki; Yuji Ishino; Masayuki Hara; Masaya Takasaki; Takeshi Mizuno
    Journal of Robotics and Mechatronics, 巻:32, 号:5, 開始ページ:1019, 終了ページ:1026, 2020年10月
    A prototype of a soft actuator for extreme environments was fabricated, and driven in a cryogenic temperature environment. Previous soft actuators cannot be used for robots in extreme environments because resin, the main fabrication material, exhibits weak environmental characteristics. Therefore, this study proposes the application of polyimide (PI) films to soft actuators. PI is characterized by excellent environmental resistance. However, the welding of PI is difficult because of its high resistance. In this study, a welding method was developed for PI films. This method does not require pretreatment, or the use of adhesives or additives to reduce resistance. Hence, an actuator that utilizes all the characteristics of PI was realized. The actuator was characterized in a cryogenic environment, which is one of the extreme environments, and was successfully driven at a liquid nitrogen temperature of 78 K. This proposed technology is not limited to cryogenic environments and is expected to provide extreme environmental resistance to existing soft robots.

  • An Equivalent Circuit Analysis and Suspension Characteristics of AC Magnetic Suspension Using Magnetic Resonant Coupling
    Arifur Rahman; Takeshi Mizuno; Masaya Takasaki; Yuji Ishino
    Actuators, 巻:9, 号:3, 開始ページ:52, 終了ページ:52, 2020年07月
    The fundamental characteristics and performances of alternating current (AC) magnetic suspension using magnetic resonant coupling are studied analytically and experimentally. Nowadays, wireless power transfer to the suspended object is required during non-contact suspension in some applications. Therefore, magnetic resonant coupling has been introduced for AC magnetic suspension to achieve self-stabilizing magnetic suspension and energy transfer to the floator simultaneously. The effect of circuit parameters for developing an experimental apparatus and performances are predicted from the solution of the equivalent circuits analytically. First, an equivalent magnetic circuit is derived and analyzed to characterize the self-inductance and mutual inductance with the gap. Second, an equivalent electrical circuit is analyzed to derive the current and force equations including magnetic parameters of the circuit. The derivation of these equations is numerically solved to study the characteristics of the primary current, the secondary current, and the force with respect to the gap and the applied frequency. The comparison between theoretical and experimental results is depicted, and the reason for differences is explained. The experimental and theoretical results show that positive stiffness is possible, which is essential for achieving self-stabilization. The self-stability is confirmed by the frequency response of the suspension system to disturbance experimentally.

    <p>A mass measurement system using relay feedback of velocity was developed. In this system, the velocity of the object was fed back through a relay with hysteresis. Although the efficacy of the proposed method has been already confirmed experimentally, it was subject to a drift mainly because only the velocity was fed back. To prevent such a drift, a spring element was added to produce restoring force. However, smaller drifts still occurred, and the trajectory of the object fluctuated. To eliminate such fluctuations, intermediate control is introduced. It succeeds to eliminate fluctuation of the trajectory in the developed apparatus.</p>

    <p>A magnetic suspension system with three flux-path control mechanisms are developed to achieve three-dimensional positioning of the suspended object (floator). In the flux-control mechanism, a ferromagnetic control plate is located in the lateral direction of the magnetic source (permanent magnet). It was shown that the attractive force acting on the floator could be varied by moving the control plate in the vertical direction. In addition, the lateral force was generated by using two control plates located on both sides of the floator and moving them differentially. In this work, an apparatus is fabricated which has three flux-path control mechanisms. The configurations of the apparatus are described. Stable suspension is achieved and basic characteristics are studied. In addition, 3-degree-of-freedom (3-DOF) control suspension is achieved by moving three control plates individually. The 3-DOF control is evaluated by moving the floator in circular orbits.</p>

    <p>Force measurement using zero-compliance mechanism is proposed and studied experimentally. A zero-compliance mechanism is composed of two suspensions connected in series; one of them is operated to cancel the deflection of the other so that the total length of the suspension is maintained even if force acts between the ends. In the proposed measurement system, one of the ends becomes the point of force and the point of the connection becomes the detection point. The force is estimated from the displacement of the detection point. An apparatus is fabricated for experimental study to show the validity of the proposed measurement method. Double series magnetic suspension is used to achieve zero compliance. In the apparatus, the motions of two suspended objects (floators) are controlled with a single electromagnet. Each floator is supported by leaf springs to move in the vertical direction translationally. The attractive force of the electromagnet directly acts on the first floator in which a permanent magnet is installed. The motion of the second floator is controlled indirectly through the attractive force of the permanent magnet. To achieve the zero compliance characteristic, PID control is applied to the second floator. It is confirmed experimentally that the deflection of the second suspension, i.e., the distance between the first and second floators, is proportional to external force acting on the second floator. This result indicates that the force can be estimated for the deflection of the second suspension. It is also demonstrated that dynamic force can be measured by the proposed method.</p>

    <p> A three-dimensional force measurement instrument is designed and developed by considering the basic principle of zero compliance mechanism. In the proposed system, the point of force and the detection point are connected in series and suspended with leaf springs. One of the suspensions operates to cancel the displacement of the other. If any force is applied at point of force that causes displacement, the detection point displaces proportionally to cancel out the displacement of the point of force. As a result, zero compliance is achieved at the point of force and applied force can be measured from the displacement of the detection point. This paper presents the design and construction of a three-dimensional force measurement instrument and the effectiveness of the proposed system is demonstrated by the experimental result of the vertical-direction force measurement.</p>

    In this paper, we explained a pneumatic film actuator fabricated by molding process. In our previous research, a bending type actuator have been developed. The bending motion is occurred by pleated structure. The structure is formed by folding process of films. The folding process is performed manually and is complicated. Additionally, the pleated structure tends to be broken by repetitive driving. In this study, a molding process was developed for fabricating a structure that causes bending motion. By pressing a mold against polyimide film, the bending structure is formed. Fabricated actuators are evaluated at room temperature. The molding type actuator has the same performance as precious one.

    Our previous studies discovered that small particles scattered at the bottom of a water-filled rectangular container align at specific positions when the container is laterally oscillated at specific frequencies. Also, a batch manipulation method of submillimeter-scale small particles was proposed by using this unique phenomenon. In the present study, we attempt to develop a method to separate small particles with various sizes by using the lateral oscillation of a rectangular container. This paper considers lateral fluid velocity distribution in the rectangular container to reveal how the distribution affects the behavior of the small particles, and examines the possibility that the small particles with various sizes can have different behaviors.

    人は物体表面をなぞった時,皮膚の振動を知覚することで物体の粗さを感じると考えられている.その粗さ感覚を提示する装置として多くのデバイスが開発されている.しかし,500Hz以上の人の振動知覚閾値は調べられておらず,その周波数以上の振動は考慮されていないことが多い.そのため,粗さの感覚を再現するのに適切な周波数帯域は分かっていない.そこで,500 Hz以上で人の振動知覚閾値が測定可能な実験装置を開発した.

    Previously, a tactile display using surface acoustic wave which is a kind of ultrasonic vibration has been developed and can render tactile sensation like roughness. Basic principle is friction reduction induced by the wave and its control. Switching the wave at certain intervals results in vibrations on user's finger surface. To consider realistic rendering, frequency range of the vibration to be presented on the display will be discussed. Aim of this research is to investigate vibration presentation with frequency more than 500 Hz. Amplitude modulation of excited ultrasonic wave was confirmed as frequency response of amplitude modulation. The modulation like 10 kHz was observed. Output vibration as tactile display was also observed with an experimental setup. Mechanical vibration up to 10 kHz was acquired, successfully. Frequency characteristics were also observed.

    Our previous studies have proposed active self-touch in which experimental participants can voluntarily touch a fake/virtual body as well as their own body by using a robotic master-salve system when experimentally manipulating sense of body ownership. This paper introduces a novel experimental platform that can control temperature displayed to the real and fake bodies by means of thermal displays in active self touch. Using the experimental platform, we aim at revealing whether the sense of body temperature is essential for human body perception and how much temperature difference between the real and fake/virtual bodies is acceptable to consider the fake/virtual body as our own body. In the present study, the basic characteristics and performances of the developed platform were evaluated and the applicability to manipulate the sense of body ownership was verified by conducting a simple cognitive neuroscientific experiment.

    <p>A switching stiffness control and a modified variable stiffness control were applied to reduce vibration in the lateral directions in active magnetic suspension system with electromagnets operated in the differential mode. The magnetic suspension system using the attractive force between magnetized bodies is inherently unstable in the normal direction so that feedback control is necessary to achieve stable suspension. In contrast, it is usually stable in the lateral directions because of the edge effects in the magnetic circuits. However, damping in the lateral directions is poor so that vibration is easily induced. In this work, a switching stiffness control was applied to attenuate such vibration. The effectiveness of the switching stiffness control was confirmed experimentally. In addition, a modified control method that varies stiffness continuously was proposed to overcome problems occurring in switching. The efficacy of the modified control method was also confirmed experimentally.</p>

    <p>A wind-tunnel system for spinning body has been proposed to measure hydrodynamic forces acting on the body. In the proposed system, the body is suspended and rotated by electromagnets. The forces are measured from the control signal for suspension. In the previously fabricated apparatus, eight electromagnets were placed around a wind-tunnel. An optical displacement sensor was used to detect the three-dimensional positions of the body. Stable suspension and three-dimensional positioning of the body were achieved. However, it had several problems; the test section area was rather small and vibration was induced by flowing wind to the floator. To solve such problems, a new wind-tunnel using magnetic suspension is developed. It has two and a quarter times test section area. The position sensor is improved to operate in a differential mode in all the directions. Stable suspension and rotation of the floator are achieved. The floator is kept stably without vibration even in the face of wind. The hydrodynamic forces acting on the spinning floator are measured.</p>

    <p>A new over-flow prevention valve with a trigger mechanism is designed, fabricated and studied experimentally to evaluate its performances. Loading arms are used to transfer combustible fluid such as oil between tankers and tanks. A loading arm is equipped with an over-flow prevention valve for safety. This valve stops the fluid flow when the fluid exceeds a threshold level in a tank. It must be composed of mechanical elements solely because electric components may induce combustion. Therefore, it uses a pneumatic circuit to detect the fluid level and close the valve. The fabricated valve utilizes positive pressure caused by the height difference of fluid level between the tank and the sensor probe instead of negative pressure that was used in a conventional valve. However, the positive pressure is insufficient to close the valve directly. Therefore, a trigger mechanism is introduced between a piston pushed by the positive pressure and a locking mechanism keeping the valve open. This mechanism generates sufficient force to release the lock and close the main valve from the force pushing the piston. The concept, operation principles and the pneumatic circuit design are presented. Experiments simulating actual operation are carried out with the fabricated valve. The sensor probe is inserted into the water with a constant speed by a single-axis robot instead of flowing oil into the tank. The relation between the velocity and the depth when the valve closes are studied experimentally.</p>

    <p>This paper treats a relay-feedback mass measurement system that uses a relay with hysteresis and feeds back the velocity of the object. The measurement system has an on-off relay with hysteresis and switches force acting on the object in relation to its velocity. Such nonlinear control induces a limit cycle. The mass of the object is determined from the period of this cycle. In previous study, the actual trajectory of the limit cycle was different in shape from the theoretical one so that the prerequisites of the estimation formula were not satisfied. The delay of the velocity sensor is a main factor of such degradation. In this paper, the effect of the delay on mass estimation is investigated experimentally and analytically. In addition, an estimating equation including this effect is derived. Experimental result supports the validity of the derived estimating equation.</p>

    <p>A wind tunnel system for a spinning body was developed for the measurement of the hydrodynamic forces acting on the body. In that system a ferromagnetic sphere (body) was suspended and rotated by electromagnets. The forces acting on the body were measured from the control signal for suspension. However this existing arrangement is not still appropriate to observe accurate hydrodynamic phenomena around the floating object because the size of the wind tunnel is only 60×60mm. It is required to enlarge the size to reduce the interferences with the walls. In this work, a wind-tunnel system of 100×100mm is proposed to be fabricated. Before the development of the system, the electromagnetic analysis for the system has been carried out. A 3D model of the arrangement is taken in consideration for the analysis. The magnetic flux distributions as well as magnetic force acting on the suspended object are obtained. The magnetic flux densities are analyzed for the variation of current in electromagnets. Actual force acting on the body is also measured. It is observed that the experimental results support the results obtained by numerical analysis. Stable suspension and three-dimensional positioning of the body is achieved in the developed system. Spinning of the body is realized by superimposing two-phase AC signals on the control signal.</p>

    A new configuration for rotating gyros using magnetic suspension is proposed and fabricated. Gyro is one of inertial sensors and a measuring instrument for angular velocity. The magnetically suspended gyro (MSG) was proposed in which a disk-type rotor is connected to a synchronous motor through a fluid bearing and the motor is fixed to the holder; the holder is suspended by magnetic force without any mechanical contact to achieve high-accuracy measurement. According to this concept, a six-degree-of-freedom (6-DOF) active MSG was developed. However, the MSG had to consume power for compensating the gravitational force acting on the holder by magnetic force. In addition, the miniaturization of the MSG was difficult because four pairs of electromagnets were arranged on the opposite sides of the holder. To solve these problems, a novel gyro with hybrid suspension is designed and fabricated. In this gyro, only two rotational motions of the holder are controlled by four electromagnets while the other 4-DOF motions of the holder are constrained by cross springs and a gimbal. Such configuration is suitable for reducing power consumption and also for miniaturization. This paper shows the basic concepts and measurement principles of the rotary gyro with hybrid suspension. The performance of the gyro is evaluated through the measurement of two-axis angular velocities. It is found from the measured frequency characteristics and the succeeding analysis that imperfect derivatives used in the estimation cause an interaction between the two-axis estimations. Two ways to cope with this problem are also presented.

    This paper presents an application of unbalance compensation to a rotary gyro with hybrid suspension. In this gyro, a disk-type rotor is connected to a synchronous motor through a fluid bearing and the motor is fixed to the frame of the holder. The four-degree-of-freedom motions of the holder are constrained by a cross spring and a gimbal. The two rotational motions of the holder are controlled by four electromagnets. Such hybrid suspension makes the system less damped. Therefore, high-accuracy measurement is possible by this gyro. However, one of the problems is that an oscillating component due to unbalance appears in the estimated angular velocity because the estimation is based on the control currents for regulating the relative displacement of the holder to the stator. To solve this problem, unbalance compensation is applied to remove the oscillating component. It is confirmed experimentally that the estimated signal agrees well with the reference signal.

  • Reduction of Noise in MEMS Output Signals by Kalman-filter Estimation

    In many mechanical control systems, the addition of acceleration feedback to the controller is an effective approach to improve systems dynamics irrespective to disturbances on them. The servo accelerometers are commonly used to measure acceleration accurately in a low frequency range; however, a conventional servo accelerometer attached to a system to measure acceleration makes the system rather costlier. The use of low-cost Micro-Electromechanical System (MEMS) accelerometers to measure acceleration can overcome this difficulty; however, the acceleration signals measured by a MEMS accelerometer typically contain noise. In this study, the Kalman filter technique is applied to reduce such noise as well as to make the MEMS accelerometers suitable to use in an active system. The Kalman filter technique used in this study estimates acceleration by minimizing the mean-square error of a series of measurements conducted by MEMS accelerometer over time, containing noise (random variations) and other inaccuracies. It is observed that the estimated accelerations by using the Kalman filter tend more precise than those based on measurement.

    Parallel magnetic suspension has been proposed where multiple floators are controlled with a single power amplifier. The feasibility of voltage-controlled double parallel magnetic suspension with parallel connected coils has been already demonstrated in the previous work. This study focuses on the zero-power control in a voltage-controlled double parallel suspension system with parallel connected coils. In this system, there are three methods of achieving zero-power control: feeding back the control voltage, either or the sum of the coil currents. This paper shows the conditions for the system with each zero-power controller to be controllable, and compares their performances.

    Double Series magnetic suspension is applied to force measurement. In a double series magnetic suspension system, two floators are suspended with a single electromagnet. The attractive force of the electromagnet directly acts on the first (upper) floator in which a permanent magnet is installed. The motion of the second (lower) floator is controlled indirectly through the attractive force of the permanent magnet. When PID control is applied to the second floator, the first floator displaces proportionally to external force acting on the second floator. Therefore, the force can be estimated for the displacement of the first floator. When the parameters are set appropriately, even small force leads to large displacement so that the proposed measurement method is suitable for noncontact measurement of micro force. An apparatus was fabricated for experimental study on the proposed measurement method. Its effectiveness was demonstrated experimentally.

    Extra low-power magnetic suspension system is achieved using solely solar power. Presently, solar cells have become more efficient and cost-saving year by year. In this work, a solar power generation technique is combined with zero-power control magnetic suspension. The zero-power control is achieved by converging the control current to zero in the steady states where the bias force generated by a permanent magnet is balanced with the gravitational force. Therefore, the steady-states power consumption becomes virtually zero in this suspension system. However, peripheral devices including sensors and controllers need power in both transient and steady states. Hence, the power consumed in the peripheral devices becomes dominant. In this work, dedicated power-saving peripheral devices are fabricated. It is observed that the average power consumed by the electromagnet is 20[mW] for suspending a 90-gram mass, and the power consumed by the peripheral devices is 13[mW]. In contrast, a conventional system consumes a few watts to suspend a floator of the same dimensions. The solar cells used in the apparatus has a maximum power capacity of 2[W] under a typical summer sunlight (approximately 120[klx]). The fabricated system can achieve stable suspension even under a illuminance of a fluorescent lamp of 5[klx].

    弾性表面波リニアモータに使用するステータ振動子の大面積化のために圧電材料と非圧電材料を組み合わせる間接励振という方法を用いる.複数の振動子で励振させた場合,スライダを駆動するのが困難な範囲が存在する.従来よりも交差指幅の広い振動子を用いたが,弾性表面波の励振部より波を一様かつ広範囲に励振すると効率が低下する問題がある.本研究では駆動周波数の調整によって励振範囲を選択し,効率の改善を目指す.

    Extra low-power suspension in the gravitational field of ground is achieved by a magnetic suspension system whose power source is solely a solar generator. Presently, solar cells become more efficient and cost-saving year by year. In this study, photovoltaic power generation technique is combined with the zero-power magnetic suspension. The zero-power control achieves the steady state in which the attractive force produced by a permanent magnets balances the weight of the floator and the control current converges to zero. Therefore, the power consumed for suspension is very small. However, the peripheral devices including sensors and a controller need power for their operations. The consumption power in the peripheral devices becomes dominant in the total power in the steady state. In this work, dedicated power-saving peripheral devices are newly fabricated. The average consumption power in the electromagnet is 20mW to suspend a 90-gram mass, while the consumption power in the peripheral devices is 13mW. The photovoltaic cells used in the apparatus has a maximum power capacity of almost 2W in the summer sunlight of 120klx. The system achieves stable suspension even under the illuminance of a fluorescent lamp of 5klx in the standalone.

    Flux-path control magnetic suspension using flux concentration is proposed and studied both analytically and experimentally. The proposed system used control plates made of permanent magnet instead of ferromagnetic material. It was shown that flux-concentrated type can produce larger suspension force than the conventional flux-interrupted type. However, it was difficult to achieve stable suspension since the control (variable) force was not so large. In this paper, to solve such a problem, the characteristics of the suspension system are studied by finite element analysis. The effects of the direction of motion, the operating positions and the shape of the control plates are investigated. An experimental apparatus with a variable flux-path unit using flux concentration is developed based on the analytical result. A single-axis stable suspension is achieved by applying PD control in the developed apparatus.

  • Double Electrostatic Suspension System Using Variable Capacitor

    Voltage control using a variable capacitor and floator position estimation are proposed for designing a low-cost electrostatic suspension control system. When an electrostatic actuator and a variable capacitor are connected in series to a constant power supply, the voltage applied to the suspension system can be changed by varying the capacitance of the variable capacitor because the electrostatic suspension system can be treated as a capacitor. Moreover, the voltage is determined by these capacitances and so the floator position can be estimated from the voltage applied to the suspension system and the capacitance of the variable capacitor. The proposed voltage control system enables electrostatic suspension without a high-voltage amplifier or direct floator position detection. Therefore, this control system can reduce the total cost of electrostatic suspension systems. The principle of the proposed self-sensing control is described using a basic electrostatic suspension model. The position of the floator was estimated according to this principle. Self-sensing suspension was achieved by feeding back the estimated signal.

    Printed-circuit boards are widely used for miniaturizing electronic equipments. According to the demand, diameter of holes in the boards is decreasing. There is a problem in their fabrication processes, in which they should be cleaned in water. After the cleaning process, water remains in the small holes. The remained water contains chemical material and/or dusts and might cause damage of the boards in the future. Conventionally, air pressure has been used to remove the water in the boards. But the method is not valid for holes that have bottoms inside neither for much smaller holes. Heating could be an alternative method, but this method might leave chemical material in the water and cause deflection of the board. In this research, a new dewatering method has been proposed. The method utilizes standing wave of ultrasonic wave in air. An experimental apparatus was organized to observe the ultrasonic dewatering and consisted of an ultrasonic transducer and a reflector. Proposed dewatering was observed successfully. The sound pressure in the standing wave was measured by a microphone. A condition for successful dewatering was discussed with reference to the distribution of the sound pressure.

    A vibration-type measurement system characterized by the use of an undamped dynamic vibration absorber has been developed. However, inevitable damping in the absorber may cause measurement error. A new method of measuring mass is proposed to overcome this problem. The measurement system utilizes the fixed point of a mass-spring system with a dynamic vibration absorber so that the mass is estimated regardless of damping in the absorber. A phase-looked loop (PLL) is used to achieve tuning. The principle of measurement is described on the basis of a mathematical model. A measuring apparatus was designed and fabricated, and several of its basic characteristics were studied experimentally. Damping of the primary system was found to affect fixed point formation. By reducing the damping of the primary system by a voice coil motor, the measurement conditions were achieved. The efficacy of the apparatus was studied both analytically and experimentally. The measurement conditions were realized automatically by the PLL. Mass measurement was performed while the PLL was operated; the average measurement error was within 0.21 [%].

    Multiple electrostatic suspension suspends multiple floators with a single power amplifier. The controllability of double parallel suspension was previously analyzed and the conditions to be controllable were shown. To ensure the analytical results, single-DOF suspension systems were fabricated, and a double parallel electrostatic suspension system consisted of these systems. The feasibility of double parallel electrostatic suspension was demonstrated experimentally. Dynamic characteristics of double parallel electrostatic suspension were studied based on step responses and frequency responses.

    In series-type multiple magnetic suspension systems, multiple floators are suspended in tandem by one electromagnet. The nearest floator to the electromagnet is directly suspended by the electromagnet. The others are indirectly suspended by the attractive force due to the magnetization of the floators. The controllability and observability of series-type multiple magnetic suspension systems with an arbitrary number of floators are discussed. They are controllable and also observable even when only the displacement of the floator nearest to the electromagnet is detected. A series-type multiple magnetic suspension system was fabricated in order to verify the analyses experimentally. In the fabricated system, magnetic suspension units that are equipped with a sensor and an electromagnet are used instead of normal floators to carry out experiments in various conditions. As the first step to realize the levitation of multiple floators using one electromagnet and one sensor, a basic trial was carried out in the fabricated system.

  • Zero-Power Control of Parallel Magnetic Suspension Systems

    This paper discusses the feasibility of zero-power control in parallel magnetic suspension systems. In parallel magnetic suspension systems, multiple floators are suspend with a single power amplifier. The zero-power control has been used in magnetic suspension systems with permanent magnets providing bias flux. This control realizes the steady states where the attractive force produced by the permanent magnets balances the weight of the suspended object and the electromagnet coil current converges to zero. This paper shows that parallel magnetic suspension systems incorporating zero-power control can assign the poles arbitrary if the original parallel suspension systems are controllable. The feasibility of the zero-power control in a parallel magnetic suspension is demonstrated experimentally.

  • Application of Feedforward Control to A Vibration Isolation System Using Negative Stiffness Suspension

    This paper presents a vibration isolation system using negative stiffness suspension. The vibration isolation system is developed by combining a positive stiffness suspension in series with a negative stiffness suspension. The developed system could realize zero-compliance to direct disturbance, as well as ground vibration isolation. In the previous system, the ground vibration and, the static and low frequency sinusoidal direct disturbances were efficiently suppressed. However, there was a reverse action in case of impulse or step wise disturbance. Therefore, a peak was appeared which was, sometimes, larger than the displacement caused by the step load. This unpleasant response might hamper the objective function of many advanced systems. In this research, a feedforward controller is added in combination with zero-power control to overcome this problem. Some experimental results are presented to verify the proposed control system in a vibration isolation apparatus.

  • Development of Three-Axis Active Vibration Isolator Using Displacement Cancellation Technique

    A three-degree-of-freedom (3-DOF) active vibration isolation system using displacement cancellation control technique is developed. The displacement cancellation concept is presented and implemented in this research to obtain zero compliance of vibration isolation table against direct static force as well as to suppress the dynamic disturbances acting on the isolation table. In the displacement cancellation control technique, relative movements of the vibration free table are followed with I-PD control and movements of the middle mass respect to base are controlled with PD control. The corresponding controllers are designed in such way so that actuator can generate opposite force against disturbance to cancel the effect of displacement of the middle mass on the vibration isolation table, which finally leads zero compliance of the isolation table. Voice coil motors (VCMs) are used for getting linear actuating effect and corresponding displacements of the table are detected by eddy-current gap sensors. The experimental results showed that the developed system with displacement cancellation mode control has capability to maintain zero compliance against direct static force in the 3-DOF motions associated with horizontal translations and a vertical rotation. Moreover experiments have been conducted to measure the dynamic responses of the vibration isolation table to direct disturbance.

    A flux-path control magnetic suspension system with multiple magnetic sources is realized. The principle of the flux-path control magnetic suspension system is to control flux from a permanent magnet to the floator, and the attractive force acting on the floator by the motion control of control plates inserted between the permanent magnet and the floator. Stable suspension and 3-DOF control with a single magnetic source was achieved. However, the horizontal control force was much less than the vertical control force. Multiple magnetic source system can overcome such problem. A variable flux-path unit is developed for the realization of multiple magnetic source system. An experimental apparatus with two variable flux-path units is constructed. Stable levitation is achieved by applying PD and PID controls. In addition, stable levitation with zero-power control is also achieved.

    The feasibility of parallel magnetic suspension is studied experimentally. Parallel magnetic suspension suspends multiple floators with a single power amplifier. Parallel magnetic suspension systems are classified according to the number of floators (multiplicity) , the output type of amplifier and the connection method of coils. This paper focuses on the current-controlled double suspension system with series connected coils. An experimental system is built by combining two magnetic suspension systems. A simultaneous stable levitation of the two floators was achieved by using PD control with a single power amplifier. Several dynamics characteristics were measured. They agreed with simulation results in tendency.

    The controllability of gyroscopic systems is discussed based on their basic analytical models. Two rotational motions of the rotor interacts each other due to gyroscopic effects. They are usually controlled with two control inputs in totally active magnetic bearing systems. This report treats gyrosocpic systems with a single control input. The conditions are clarified under which the systems become controllable.

    This paper presents a method of increasing the load capacity of magnetic suspension systems. The limits of coil current and suspension gap determine the load capacity. In the PID-controlled system, the displacement is kept zero and the coil current increases when load is added to the floator. In contrast the current is kept zero and the gap decreases in the zero-power controlled system. As a result the load capacity is determined by the current limit in the former and the gap limit in the latter. It can be increased by switching them each other. The switching stiffness control is applied for this purpose in this paper. Experimental results demonstrate the operating range is extended almost twice.

    The paper proposes multiple magnetic suspension systems. The concepts are presented by using their basic models. They are classified according to multiple structure, power amplifier and coil connection. According to the first item, they can be divided into series and parallel. This paper mainly treats the latter. The controllability and the observability of each parallel suspension system are discussed based on its mathematical model. The concept of sensorless magnetic suspension is stretched to the multiple systems. The feasibility of parallel magnetic suspension is demonstrated by simulation.

    The effects of surface tension on picking up a minute object by a water drop were studied experimentally. The self-centering effects of the proposed method of picking up a microchip was demonstrated in the 1st report. In this method, the stability of forming a drop and sufficient capillary force for lifting up the chip are important. This paper investigated the effect of liquid surface tension on them by using isopropanol (IPA) and its water mixture. The surface tension of water is about three times that of IPA. It was found that the maximum wetting angle on the top of nozzle increased as the ratio of IPA to water decreased. As a result, larger drops were enable to be formed as the ratio of IPA decreased. The adsorption force of a drop was measured for IPA-water mixtures. It was found that the adsorption force of a drop was sufficient to lift up a microchip.

    This paper presents a control system for active magnetic bearings (AMBs) considering the motions of the stator. AMBs require active control for stable support of the rotor. Many control methods for AMBs have been proposed. Most of them are designed with no regard to the stator motions because the stator is usually fixed on the base. However, in some applications, the stator moves with the object in which the AMB is mounted. In this paper, the influences of the stator motions on the relative angle of the rotor to the stator are investigated both theoretically and experimentally. In addition, the signals estimated by a disturbance observer are used to compensate the influences. The influences become remarkable at a low frequency range. The upper side of the remarkable range extends to higher frequency range when the gyroscopic effect is large. The influences are cancelled by the compensation using the observer. The effect of the cancellation depends on the estimation speed of the observer.

  • Application of Rotor Unbalance Compensation to an AMB-Based Gyroscopic Sensor

    Rotor unbalance in an AMB-based gyroscopic sensor is studied in this paper. An AMB-based gyroscopic sensor has been proposed to realize a high-accuracy, low-cost and compact gyroscopic sensor. In this sensor, an active magnetic bearing (AMB) is applied as a rotating gyro, which is an instrument for measuring angular velocity. The relative position and attitude of the AMB rotor to the AMB stator are maintained using magnetic forces. Two-axis angular velocities of a measurement object are estimated from the control currents required to cancel the gyroscopic torque acting on the AMB rotor. However, the estimated signals of angular velocities include several undesirable frequency components. These components are caused by rotor unbalance and the induction motor used to spin the AMB rotor. A beat appears due to composition of these components. The beat component cannot be eliminated by filtering because it is in the measurement bandwidth of the AMB-based gyroscopic sensor. In this study, two unbalance compensation methods are applied to the AMB-based gyroscopic sensor to eliminate the beat component from the estimated measurements of angular velocities. The efficacy of each compensation method is examined experimentally.

    A new control system for electrostatic actuators was applied to electrostatic suspension. This control system was designed to use a variable capacitor connected with an electrostatic actuator in series. A high voltage was applied to this connection. The voltage applied to the actuator was controlled by varying the capacitance of the variable capacitor. An experimental apparatus was fabricated in order to study the controllability of electrostatic force using this control system. The experimental results show that electrostatic force can be controlled both statically and dynamically. Another experimental apparatus was fabricated for demonstrating the feasibility of electrostatic suspension. This apparatus was able to control the 3-DOF vertical motions of the suspended object. Non-contact suspension was achieved with the developed control system using variable capacitors.

    This paper proposes a new method of handling microchips. The process of handling is as follow. First, a water drop is made at the head of the nozzle. Second, the nozzle downs so that the water drop touches the chip. Third, the nozzle is lifted up. Then the chip comes to the bottom of the water drop automatically due to the gravitational force, which is called self-centering effect. Then the water drop is suctioned for the chip to be held at the head of the nozzle. This method has an advantage of catching up and positioning a chip displaced from the center of the nozzle due to the self-centering effect. Fundamental performances of this method are studied experimentally.

    In the flux-path control magnetic suspension system, the force acting on the floater is controlled by moving a control plate made of ferromagnetic material, which is located between the permanent magnet and the floater. In this paper, the three-dimensional attractive forces acting on the floator were measured with a manufactured load cell and two sets of plate springs with strain gauges. The force actuating in the vertical direction is measured with the load cell. The force actuating in the horizontal direction is measured with the plate springs with strain gauges. These measurements clarify the relations between the positions of the control plates and the three-dimensional attractive forces. In addition, stable three-dimensional positioning was achieved by applying PD control. PD control is also applied to the flux path control modules to provide them sufficient stiffness and damping property to suspend the floator. In addition, several dynamic characteristics were measured in each direction.

    Surface acoustic wave (SAW) linear motor is a kind of ultrasonic motors. The advantages of the SAW linear motor is thin structure, high force, high speed and precise positioning. On the other hand, the motor has a problem with wear of contact surface. The SAW linear motor consist of a LiNbO_3 as a stator transducer and a silicon substrate with distributed projections as a slider. However, the stator transducer material is easy to wear out due to friction drive. Moreover the silicon projections enhanced wearing. Lifetime of the motor is reduced by the wear of the stator. To solve this problem, the silicon substrate with segment structured diamond-like carbon (S-DLC) films is applied as the slider instead of the silicon slider with projections. The films are expected to increase abrasion-resistant performance of contact surface and acquire the same driving characteristics as the conventional silicon slider. This report presents installation of the films on the slider surface and successful work of the motor. Observation of its performance is also indicated to be compared with the conventional one. The films deposition on a stator transducer is introduced. Successful driving of the motor with the stator transducer is also described.

    A new gyroscopic sensor using active magnetic bearing (AMB) is studied both theoretically and experimentally. The proposed sensor works as a two-axis gyroscopic sensor and also as a three-axis servo-type accelerometer, which utilizes the control function of AMB. Angular velocities and accelerations are estimated from the control signals for canceling gyroscopic torque and inertial forces acting on the shaft of the AMB. In measuring two-axis angular velocity simultaneously, the control signals canceling inertial torque must be considered in addition to the gyroscopic toque for precise measurement. This paper presents the principles of two-axis angular velocity and acceleration measurement by AMB. In order to investigate the feasibility of the proposed sensor, several basic studies are carried out with a conventional-size AMB.

    Mass measurement using a relay feedback system was studied experimentally. The measurement system has an on-off relay with hysteresis and switches force acting on the object in relation to its velocity. Such nonlinear control induces a limit cycle in the feedback system. The mass of the object is determined from the period of this limit cycle. The apparatus manufactured for experimental study uses two voice coil motors (VCM's), one of which is for driving the object and the other is for generating prescribed disturbances. The effects of system parameters and disturbances on measurement accuracy were examined experimentally.

  • Ultra Low-Velocity Control of a Surface Acoustic Wave Linear Motor

    A surface acoustic wave (SAW) linear motor is a kind of ultrasonic motor. The advantages of the SAW linear motor are thin structure, high thrust force, high velocity and precise positioning. The relationship between applied current and output velocity is, however, unstable in the low velocity range due to the friction drive principle. Therefore the SAW linear motor cannot obtain stable driving without feedback control in the low-velocity region. In this research, to realize low velocity, a pulse width modulation (PWM) control and flexible slider structure are employed. Flexible structure is installed to cancel vibration due to the PWM carrier wave. A lower velocity in the unstable range is realized. Moreover we change the calculation algorithm for the slider velocity measurement. As a result, the SAW linear motor can be driven at an ultra low velocity of 30&mu;m/s. Additionally, driving characteristics are improved using a feedforward controller.

  • Flux-Path Control Magnetic Suspension System Using Voice Coil Motors

    A novel magnetic suspension system with three flux-path control modules was developed. The module consists of a ferromagnetic plate, a voice coil motor (VCM) for driving the plate and a displacement sensor for detecting the position of the plate; the sensor is comprised of a V-shape plate spring and four strain gauges pasted on it. The ferromagnetic plate is inserted into the gap between a permanent magnet and a suspended object (floator). The lateral position of the plate is controlled by using the VCM and the sensor. Since the flux from the permanent magnet to the floator varies according to the position, the amplitude and direction of the attractive force acting on the floator can be adjusted with multiple modules. Stable suspension was achieved by applying PD control. A fluctuation was observed in the position of the floator. It was reduced by feeding back the lateral motions of the floator. The two-dimensional and three-dimensional noncontact manipulation of the floator was also achieved in the developed magnetic suspension system.

  • Development of a three-axis active vibration isolator using zero-power control

    This paper presents the development of an active 3-degree-of-freedom (DoF) vibration isolation system using zero-power magnetic suspension. The developed system is capable to suppress direct disturbances and isolate ground vibrations of the 3-DoF motions, associated with vertical translational and rotational modes. Two categories of control strategy for the actuators are proposed, i.e., local control and mode control. The latter method allows to overcome limitations of the poor performances for rotational modes exhibited by the former. A mathematical model of the system is derived and each DoF motion is treated separately for the control system. It is demonstrated analytically that the infinite stiffness to static direct disturbances can be generated and the resonance peak due to floor vibration can effectively be suppressed for the system. Moreover, the experiments have been carried out to measure the static and dynamic responses of the isolation table to direct disturbances, and transmissibility characteristic of the isolator from the floor. The results indicate good vibration isolation and attenuation performances, and show the efficacy of the developed isolator for industrialization.(c)2007 IEEE.

    Vibration isolation system using zero-power magnetic suspension is modified. A suspension spring is introduced in parallel with a series connection of a zero-power-controlled magnetic suspension and a normal spring that were used in the previous works. It can reduce the load force that the zero-power magnetic suspension has to bear. A basic configuration of the modified vibration isolation system is shown. It is demonstrated both analytically and experimentally that the modified system maintains infinite stiffness against static direct disturbance even if such a spring is added. The characteristics to dynamic direct disturbances are also studied experimentally.

    Surface acoustic wave (SAW) linear motor is a kind of ultrasonic motors. The SAW linear motor has several advantages, such as thin structure, high thrust force, high velocity and precise positioning. Relationship between applied voltage and output velocity, however, had non-linearity in low velocity range due to friction drive principle. Therefore the SAW linear motor cannot obtain stable driving without feedback control at low velocity. To realize low velocity, PWM (pulse width modulation) control and flexible slider structure are employed. The flexible structure is installed to cancel vibration due to PWM carrier frequency. In this research, PWM is applied for controlling the slider velocity. Lower velocity in non-linear range is realized. Influence of the flexible structure upon precise positioning is investigated.

    This paper investigates the applicability of pneumatic actuator to active vibration isolation system using negative stiffness. First, a control method of realizing negative stiffness with an pneumatic actuator is derived based on a single-degree-of-freedom model. Its efficacy is verified in a fabricated single-axis apparatus. Then a zero-compliance mechanism is realized by connecting a suspension with negative stiffness and a suspension with positive stiffness; both the suspensions use fabricated pneumatic actuators. Next, such zero-compliance mechanism was also achieved in a developed three-axis active vibration isolation system using the pneumatic actuators. The dynamic characteristics of the system to direct disturbance were estimated experimentally.

The serial connection of a normal spring and a suspension system with negative stiffness enables the isolation system to have low stiffness for vibration from the ground and high (theoretically infinite) stiffness against direct disturbance acting on the isolation table. A control method of realizing negative stiffness with a linear actuator is presented in an analytical form. The validity of this method is confirmed experimentally with an apparatus equipped with a voice coil motor. It is also confirmed experimentally that high stiffness against direct disturbance on the isolation table can be achieved in the proposed vibration isolation system.

    A flux-path magnetic suspension system was fabricated in which the three-degree-of-freedom motions of the floator was actively controlled. In this system, a control plate with four rectangular permanent magnets for magnetic concentration were used instead of ferromagnetic control plates in the conventional flux-path magnetic suspension system to increase the suspension force. The three-degree-of-freedom motions of the control plate were controlled with four differential electromagnetic actuators according to the motions of the floator. Contactless suspension was achieved by applying PD control in the fabricated suspension system.

The system makes it possible to estimate the force from the displacement of a detection point without displacing the point of force. The efficacy was proved by an experimental apparatus uses a parallel springs and a voice coil motor as an actuator. However, the accuracy of measurement was limited because of independent four single-axis measurement units. To solve such a problem, a structurally-integrated measurement unit to is developed. In this work, an apparatus for 3-component force measurement is designed and fabricated.

    The characteristics of the AC magnetic suspension system using magnetic resonant coupling are studied experimentally. The treated suspension system has self-stabilization characteristics so that noncontact suspension can be achieved without any active control. An experimental apparatus has been fabricated which has three pairs of primary and secondary electromagnets for three-axis suspension; the three primary electromagnets are fixed to the stator, and the three secondary electromagnets are fixed to the floator. Stable noncontact suspension has been achieved by supporting the stator through springs and dampers from the base. The characteristics of the achieved suspension system are studied experimentally.

    A switching stiffness control was applied to reduce vibration in the lateral directions in active magnetic suspension system with electromagnets operated in the differential mode. The magnetic suspension system using the attractive force between magnetized bodies is inherently unstable in the normal direction so that feedback control is necessary to achieve stable suspension. In contrast, it is usually stable in the lateral directions because of the edge effects in the magnetic circuits. However, damping in the lateral directions is poor so that vibration is easily induced. In this work, a switching stiffness control was applied to attenuate such vibration. The effectiveness of the switching stiffness control was confirmed experimentally. In addition, a modified control method that varies stiffness continuously was proposed to overcome problems occurring in switching. The efficacy of the modified control method was also confirmed experimentally.

    The completely passive levitation of a column-shaped graphite object is achieved. Graphite is a typical diamagnetic material. Diamagnetic materials have a property of generating repulsive force in magnetic field. Most diamagnetic levitation systems use high-oriented pyrolytic graphite (PG) sheets because sufficient force for levitation is obtained easily. In contrast, a column-shaped graphites are the target of levitation in this work. Experimental apparatus for diamagnetic levitation is fabricated. The apparatus uses a two-dimensional Halbach array made of cubic neodymium magnets. The magnetic fields in the apparatus are analyzed numerically and measured for comparison. It is shown that the stable diamagnetic levitation of a column-shaped graphite is achieved. The floator is fabricated by combining the pencil leads made of graphite. The diamagnetic forces acting on the floator are measured. In addition, the effects of anisotropy of graphite on the levitation characteristics are discussed.

    A mass-spring system with a dynamic vibration absorber has a fixed point in its frequency response curves. A method of measuring mass using this property was proposed. It has an advantage that mass is estimated independently of the damping in the absorber. The developed system was characterized by using a phase-looked loop to achieve the tuning condition. However, because the actuator producing the harmonic force was mounted on the base, the reaction force was transmitted to the surrounding structure. It may cause a severe vibration of the surrounding structure. Therefore, it is necessary to prevent transmission of force to the surrounding structure in measuring. In this paper, a new type of mass measurement system is proposed which uses an inertial-mass vibrator to reduce the transmitted vibration. The tuning conditions are derived for both systems with a damped absorber and with an undamped absorber. The principles of measurement are described based on a mathematical model. An experimental apparatus is designed and fabricated. The efficacy of the measurement system with an inertial mass-type vibrator is studied both analytically and experimentally.

    Recently, the touch panel has been widespread as computer interface. Using the touch panel is easy because of intuitive operation, but it is difficult for a visually impaired person who cannot get the visual information. In order to improve this problem, tactile display using sheet-like ultrasonic transducer has been developed in previous research. By this device, when a touch panel is operated, user can get tactile feedback, and it is possible to recognize an icon and a window. However, at the present stage, it cannot be mounted on a large-sized touch panel. So, we aim at development of tactile display using sheet-like transducer which can be mounted on a large-sized touch panel. In this paper, evaluation of the couplant used for the sheet-like ultrasonic transducer is reported.

    The completely passive levitation of a special-shaped graphite object is achieved. Graphite is a typical diamagnetic material. Because the diamagnetic materials have a property of causing repulsive force in magnetic field, it can be stabilized with a set of permanent magnets. Most recently reported diamagnetic levitation systems use high oriented pyrolytic graphite sheets because enough force for levitation is obtained easily. In contrast, this work targets objects with different shapes such as spherical or cylindrical. This paper presents several examples of the design and analysis of magnetic field produced by permanent magnetic and ferromagnetic materials. It is also shown that the stable diamagnetic levitation of pencil leads is achieved by the fabricated magnetic stator.

    An active vibration isolation system has been proposed that uses an active dynamic absorber as a servo-accelerometer in a low frequency range and a vibration control device in a high frequency range. Complimentarily, it uses an air actuator as a control device in a low frequency range and a low cost accelerometer as a sensing device in a high frequency range. It aims to develop a high performance active vibration isolation system that is lower in cost than conventional active vibration system. This report shows the effects of acceleration feedback by combining MEMS-sensed signal compared with acceleration feedback by combining servo-accelerometer signal.

    This paper presents an application of unbalance compensation for unbalance using exogenous signal synchronized with rotation to a rotary gyro with hybrid suspension. In this gyro, a disk-type rotor is connected to a synchronous motor through a fluid bearing and the motor is fixed to the frame of the floator. The four-degree-of-freedom motions of the floator are constrained by a cross spring and a gimbal. The two rotational motions of the floator are controlled by four electromagnets. Such hybrid suspension makes the system less damped. Therefore, high-accuracy measurement is possible by this gyro. However, one of the problems is that an oscillating component due to unbalance appears in the estimated angular velocity because the estimation is based on the control currents for regulating the relative displacement of the rotor to the stator. To solve this problem, unbalance compensation is applied to remove the oscillating component. It is confirmed experimentally that the estimated signal agrees well with the reference signal.

    A zero-compliance mechanism is applied to force measurement. In the proposed force measurement system, the force is estimated from the displacement of a detection point without displacing the point of force. The efficacy was demonstrated by an experimental apparatus using series magnetic suspension. Because the apparatus used magnetic force to achieve zero-compliance, the accuracy of measurement was limited because of the nonlinearity. To solve such a problem, a single-axis measurement unit has been developed which uses a parallel spring and a voice coil motor as an actuator. In this paper, the control system is designed based on the pole assignment method. The relation between the closed-loop poles and the measurement bandwidth is investigated experimentally.

    In recent years, exchanging the large amount of accurate information is required. Various tactile display has been investigated as the method of informing tactile sensation, which is one of the five senses. Tactile display using surface acoustic wave (SAW) has been studied, and Tele-touch system on tactile sensation during rubbing physical surface has been also proposed. In this system, dummy finger is proposed as tactile sensor where the dynamical vibration of the dummy skin is transformed to electrical signal while the finger is exploring on the physical surface. These dummy fingers were fabricated to simulate human finger as for their structure, form and hardness. However, vibration transmitted to the dummy finger is different in rubbing on physical surface, because each dummy finger has different stiffness and dumping. In this paper, dynamical model of the dummy finger and their different characteristic are studied for establish of Tele-touch system.

    A wind-tunnel system for spinning body has been proposed to measure aerodynamic forces acting on the body. In the proposed system, the body is suspended and rotated by electromagnets. The forces are measured from the control signal for suspension. Three-dimensional positioning and rotation of the body were achieved. However, due to the non-uniformity of the magnetic fields, the rotation around a horizontal axis suffered from drag torque caused by eddy current. In this paper, a self-spinning floating body with a function of adjusting the angle of the spinning axis is developed. The floator was suspended successfully with spinning around various axes.

    A new configuration for rotating gyros using magnetic suspension is proposed in this study. Gyro is one of inertial sensor and measuring instrument for angular velocity. In a magnetically suspended gyro (MSG), a disk-type rotor is connected to a synchronous motor through a fluid bearing and the motor is fixed to the frame of the floator. The floator is suspended by magnetic force without any mechanical contact so that high-accuracy measurement is possible. According to this concept, a 6-degree-of-freedom (DOF) active MSG was developed. However, because the MSG used magnetic attraction pulling upward against gravity, it has high power consumption. In addition, the miniaturization of the MSG was difficult because four pairs of electromagnets were arranged on opposite sides of the floator. To solve these problems, a 2-DOF active magnetically suspended micro gyro (MSMG) is designed and fabricated. In this gyro, the 4-DOF motions of the floator are constrained by a cross spring and a gimbal. The two rotational degrees of motion of the floator is controlled by four electromagnets. The gyro with such configuration is suitable for miniaturization and low-cost fabrication. This paper shows basic concepts and measurement principle of the 2-DOF active MSMG.

    Parallel magnetic suspension has been proposed where multiple floators are controlled with a single power amplifier. The feasibility of voltage-controlled double parallel magnetic suspension with parallel connected coils has been already demonstrated in the previous work. This study focuses on the zero-power control in a voltage-controlled double parallel suspension system with parallel connected coils. In this system, there are three methods of achieving zero-power control: feeding back the control voltage, either or the sum of the coil currents. This paper shows the conditions for the system with each zero-power controller to be controllable, and compares their performances.

    Series magnetic suspension is applied to force measurement. In a double series magnetic suspension system, two floators are suspended with a single electromagnet. When PID control is applied to the lower (second) floator and force acts on the lower floator, the upper (first) floator displaces whereas the lower floator is maintained at the original position. Therefore, the force can be estimated for the displacement of the upper floator. When the parameters are set appropriately, small force leads to large displacement so that the proposed measurement method is suitable for noncontact measurement of micro force. In this work, an apparatus for tri-axis force measurement was fabricated. Force measurements were carried out with the apparatus. The results show that three-dimensional forces were measured with a high resolution by the developed apparatus.

    This paper describes the effectiveness of an active vibration isolation system that uses an active dynamic absorber as a servo accelerometer in a low-frequency range and a vibration control device in a high-frequency range. Complimentarily, it uses an air actuator as a control device in a low-frequency range and a low-cost accelerometer as a sensing device in a high-frequency range. The main aim of this research is to develop a high performance active vibration isolation system that is lower in cost than conventional active vibration system. It was experimentally demonstrated that the acceleration in a low frequency range can be detected from the control input of the absorber. In addition, by feeding back the estimated acceleration, the vibration was actually attenuated.

    When we rub physical surface with pen or stylus, we can feel tactile sensation through it. The reproducing of such realistic tactile sensation is focused recently and some devices have been developed. On the other hand, many devices proposed only low frequency sensation, that frequency is considered as peak frequency of mechanoreceptor sensitivity. In this research, adding high frequency vibration to tactile sensation indication was proposed. To confirm high frequency vibration on surface acoustic wave (SAW) tactile display, its frequency response was measured. We conducted a psychological test to investigate the perceptual threshold that human can feel on SAW tactile display. We confirmed that human feel the high frequency vibration.

    Zero-compliance system is applied to micro-force measurement. The system measures the force from the displacement of a detection point without displacing the point of force. The efficiency was proved by an experimental apparatus using series magnetic suspension. It could measure the force at high resolution under the condition that the displacement of the point of force was zero. However, it used magnetic force to achieve negative stiffness so that the accuracy of measurement was limited because of the non-linearity. To solve such a problem, this study develops an experimental apparatus that consists of a parallel spring device and a voice coil motor as an actuator. Measurement tests are earned out with the apparatus.

    A novel AC magnetic suspension using magnetic resonant coupling is proposed and studied both theoretically and experimentally. The conventional AC magnetic suspension with energy transfer function has a problem that energy transfer efficiency is very low because it has a gap. In contrast, even if it has a gap, the energy transfer method using magnetic resonant coupling has high efficiency. In this paper, this method is combined with AC magnetic suspension. An experimental apparatus is fabricated for basic study. The floator was successfully suspended without control, and the self-stabilization characteristic is confirmed.

    Parallel magnetic suspension has been proposed where multiple floators are controlled with a single power amplifier. The feasibility of double parallel magnetic suspension with zero-power controller has been already demonstrated in the previous work. The zero-power control was achieved by feeding back the integral of the coil current. To achieve stable zero-power suspension, the feedback gain of the integral was positive in usual single magnetic suspension system, and negative in double magnetic suspension system. This paper shows analytically that the sign of the integral gain depends on the multiplicity (number of floators), it is positive for odd multiplicity whereas negative for even multiplicity.

    A six-degree-of-freedom (DOF) active magnetically suspended gyro (MSG) is developed and its performances are estimated. In MSG, a disk-type rotor is connected to a synchronous motor through fluid bearing, the motor is fixed to the frame and the frame is suspended by magneticforce without any mechanical contact; According to this concept, a three-DOF active MSG was developed. However, because of poor damping in the passive suspension and low resolution of displacement sensor, measurement accuracy was relatively low. To solve these problems, a totally (six-DOF) active MSG was fabricated. In this paper, the influence of displacement sensor noise on angular velocity measurement is examined. Since the totally active MSG's displacement sensor is more sensitive than the three-DOF active MSG's, the totally active MSG has less noise of measurement angular velocity than the three-DOF active MSG.

    This paper discusses the feasibility of zero-power control in voltage-controlled parallel magnetic suspension systems. Parallel magnetic suspension systems are classified into two types based on the connection of the multiple coils: series connection and parallel connection. To achieve zero-power control, the integral of current is fed back in the former type whereas the integral of voltage is fed back in the latter. It is proved that each parallel magnetic suspension system incorporating the zero-power controller can assign the poles arbitrarily when the original system is controllable. It is also shown analytically that the current converges to zero in the steady state even when stepwise disturbances act on the floators in both designed systems.

    Variable flux-path magnetic suspension using flux concentration is studied analytically It was shown that flux-concentration type can produce larger suspension force than the conventional variable flux-path system using ferromagnetic control plate. However, it was difficult to achieve stable suspension, since the control (variable) force was not so large, To solve such a problem, the characteristics of the suspension system are studied by finite element analysis. In particular, the effects of the direction of motion, the operating positions and the shape of the control plates were investigated.

    Series magnetic suspension is applied to force measurement. In a double series magnetic suspension system with PID control, the upper floator displaces when force acts on the lower floator. Therefore, the force can be estimated for the displacement of the upper floator. When the parameters are set appropriately, small force leads to large displacement so that the proposed measurement method can be suitable for noncontact measurement of microforce. An apparatus was fabricated to study the effectiveness of the proposed method experimentally.

    Variable flux-path magnetic suspension system has been proposed as one of the magnetic suspension systems, which controls the attractive force by moving a pair of control plates located between the permanent magnet and the floator. In this paper, a new variable flux-path magnetic suspension system using flux concentration is proposed. This system has permanent magnet plates as control plates while conventional system has ferromagnetic plates, so that the increase of attractive force can be expected. To verify the prediction, distribution of flux density and attractive force were analyzed by using FEM. These analyses clarified the increase of attractive force and relations between the attractive force and the distance of the control plates. To test the analytical results, an experimental apparatus was fabricated. The measurement results support the analytical predictions.

    Multiple magnetic suspension suspends multiple floators with a single power amplifier. It is classified into parallel magnetic suspension and series magnetic suspension. Parallel magnetic suspension systems are classified according to the output type of amplifier and the connection method of coils. This paper focuses on the current-controlled series-connected multiple suspension system. The feasibility of the zero-power control in the parallel magnetic suspension system with different polarities is demonstrated experimentally. The zero-power control is achieved by using PD control and introducing a minor feedback of the integral of the current. It was confirmed experimentally that the coil current converged to zero for constant disturbances in the designed control system.

    This paper presents an application of negative stiffness to carrier suspension system. The suspension is located under the center of gravity of the carrier system, which is similar to that in automobiles. In the conventional positive stiffness suspension system, the loading platform tilts to the unstable direction by inertial force during acceleration and turning. deceleration and This problem can be solved by using a suspension with negative stiffness because, the platform tilts to the stable direction, which is similar to the pendulum-type carrier. The negative stiffness is realized by zero-power magnetic suspension with disturbance feed-forward control.

    A new variable flux-path unit is developed for flux-path control magnetic suspension with multiple magnetic sources. The authors have proposed the variable flux-path magnetic suspension system as a unique magnetic suspension system using permanent magnet. This system has ferromagnetic plates between a permanent magnet and a floator. The flux from the permanent magnet to the floator, and the attractive force acting on the floator can be adjusted by the motion control of the control plates. Stable suspension and 2-DOF control with a single magnetic source was achieved. However, the horizontal control force was much less than the vertical control force. In this paper, flux-path control magnetic suspension with multiple magnetic sources is proposed. An experimental apparatus with a variable flux-path unit is developed for realizing multiple-magnetic-source systems. Basic characteristics of the apparatus are measured. Stable levitation is achieved by applying PD and PID controls. In addition, stable levitation with zero-power control is also achieved.

    In this paper, series-type multiple magnetic suspension systems are studied. Several floators are suspended in series by one electromagnet in these systems. The nearest floator by the electromagnet is directly suspended by the electromagnet. The others are indirectly suspended by the attractive force due to the magnetization of the floators. The controllability and observability of series-type multiple magnetic suspension systems that have arbitrary number of floators, and in which the nearest floator by the electromagnet is detected are proved mathematically. A series-type multiple magnetic suspension system was fabricated in order to verify the analyses experimentally. In the fabricated system, magnetic suspension units that are equipped with a sensor and an electromagnet are used instead of the normal floators to study on various conditions. As the first step to realize the levitation of multi floators using one electromagnet and one sensor, a basic trial is carried out in the fabricated system.

    This paper presents a method of increasing the load capacity of magnetic suspension systems. The limits of coil current and suspension gap determine the load capacity. In PID-controlled systems, the displacement is kept zero and the coil current increases when load is added to the floator. In contrast, the current is kept zero and the gap decreases in zero-power controlled systems. As a result, the load capacity is determined by the current limit in the former and the gap limit in the latter. It can be increased by switching them each other. The switching stiffness control is applied for this purpose. Experimental results demonstrate the operating range is extended almost twice.

However, the miniaturization of the AMB-based gyro is technically difficult because of the limitations on its design and structures. A new structure has been proposed to solve the problem. A prototype of the new gyro has been designed and fabricated. In this paper, the performance of the magnetic suspension of the prototype is evaluated from a viewpoint of frequency response. In addition, angular velocity measurement using the prototype is curried out. The accuracy of measurement is reported.

    A control method of adjusting the stiffness of suspension was proposed for magnetic suspension systems whose bias flux is provided by permanent magnets. In such magnetic suspension systems, zero-power control has often been applied. Since the zero-power magnetic suspension system behaves as if it has negative stiffness. So that it is applied to vibration isolation system. However, the amplitude of negative stiffness cannot be adjusted. In this paper, a proportional feedback is incorporated into the minor current feedback loop of the zero-power controller. It is shown that the stiffness can be adjusted by the gain of the added current feedback. This system improves static load performance for magnetic suspension system. The principle and experiment results are presented. When a gap changes in this system, the stiffness also changes. Therefore a nonlinear compensation is included in this system to improve the linearity.

    The variable flux path suspension system is a magnetic suspension system using the force of attraction between a permanent magnet and a ferromagnetic suspension object. Stable suspension and three-dimensional positioning was realized when a single magnetic source was used. However, the horizontal control force was much less than the vertical control force. This paper proposes a variable flux-path suspension system with multiple magnetic sources to make the horizontal force in the same range of the vertical force. A variable flux path module applicable to such multiple magnetic source system is developed. Stable suspension is achieved with this module. In addition, zero-power control is achieved by the feeding back the integral of current of the actuator.

    This paper presents a method of increasing the load capacity of magnetic suspension system with a PID or zero-power controller. In the magnetic suspension systems, load capacity is determined by coil current and suspension gap. In the PID controlled system, the displacement is kept zero and the coil current increases when load is added to the floater. In the zero-power controlled system, the current is kept zero and the gap decrees. The load capacity is therefore determined by the current limit in the former and the gap limit in the latter. This paper shows that the load capacity can be increased by combining both the controls.

    Surface acoustic wave (SAW) linear motor is a kind of ultrasonic motors. The advantages of the SAW linear motor are thin structure, high thrust force, high velocity and precise positioning. Relationship between applied voltage and output velocity, however, has non-linearity in a low-velocity area due to friction drive principle. Therefore the SAW linear motor cannot obtain stable driving without feedback control in the low-velocity area. Previously, to realize such low velocity, PWM control and flexible slider structure were employed. Flexible structure was installed to cancel vibration due to PWM carrier frequency. In this research, we change calculation algorithm for slider velocity measurement. As a result, SAW linear motor can be driven at a low velocity of 30mm/s. Additionally, driving characteristics is improved by using a feedforward controller.

    A gyroscopic sensor using active magnetic bearing (AMB) is studied in this paper. This sensor has been proposed to realize a compact, high-accuracy, multi-axis, and low-cost sensor. It utilizes the control function of AMB and works as a two-axis gyroscopic sensor and also as a three-axis servo-type accelerometer. Angular velocity measurement is focused in this paper. Angular velocities are estimated from the control signals for canceling gyroscopic and inertial torque acting on the shaft of AMB. In measuring two-axis angular velocity simultaneously, there is the upper limit to the measurement range since the estimation equation has zero as a frequency. Several numerical simulations and experiments with a conventional-size AMB are used to investigate the properties of the zero extensively.

    A new magnetic suspension using a variable flux-path has been proposed. The flux of the permanent magnet to floator is controlled by moving ferromagnetic plates between them. The lateral position of ferromagnetic plates is changed by an actuator. In the previous works, a 100-g steel ball was supported and controlled in three dimensions using this mechanism. The purpose of this study is to suspend a kg-order object and controlled it in three dimensions. This study shows that a one-kg steel ball can be supported by magnetic suspension using a variable flux-path mechanism.

    A novel control method of electrostatic actuators is applied to electrostatic suspension. This method uses a variable capacitor, which is connected with an electrostatic actuator in series. A constant high voltage is applied to this connection. The voltage applied to the actuator is controlled by varying the capacitance of the connected capacitor. An experimental apparatus was fabricated for studying the controllability of the electrostatic force by the proposed method. The experimental results showed that electrostatic force can be controlled both statically and dynamically. Another apparatus was fabricated for checking the feasibility of electrostatic suspension. Noncontact electrostatic suspension was achieved with the developed control system.

    This paper estimates the principle of two-axis angular velocity measurement in gyroscopic sensor using active magnetic bearing. In the sensor, angular velocities are measured based on the control signals to cancel gyroscopic toques operated to the shaft in the AMB. In measuring two-axis angular velocity at the same time, the control signals to cancel inertial toques must be considered in addition to the gyroscopic toques for precise measurement. However, effect of the considering the control signal to cancel the inertial toque never been revealed. The effect is studied in this paper.

    Surface acoustic wave (SAW) linear motor is a kind of ultrasonic motors. The advantages of the SAW linear motor is thin structure, high thrust force, high velocity and precise positioning. Relationship between applied voltage and output velocity, however, has non-linearity in a low-velocity area due to friction drive principle. Therefore the SAW linear motor cannot obtain stable driving without feedback control in the low-velocity area. Previously, to realize such low velocity, PWM control and flexible slider structure were employed. Flexible structure was installed to cancel vibration due to PWM carrier frequency. In this research, we change calculation algorithm for slider velocity measurement. As a result, SAW linear motor can be driven at a low velocity of 0.05mm/s.

    The paper proposes to apply Active Magnetic Bearing (AMB) for developing compact, multi-axis, high-accuracy and low-cost gyroscopic sensors. In the proposed sensor, angular velocity and in addition acceleration are measured based on the control signal for maintaining the relative position of the shaft to the stator in the AMB. It works as two-axis gyroscopic sensor and in addition three-axis servo-type accelerator so that the cost performance of the proposed sensor is expected to be high enough. In order to investigate its feasibility, several basic studies are carried out with a conventional-size AMB.

    Reproduction of human haptic sensation has lately attracted attention for various fields, such as virtual reality, remote control of robots, computer interfaces and so on. Previously, a novel method to provide human tactile sensation using surface acoustic wave (SAW) was proposed. A pulse modulated driving voltage excites temporal distribution of standing SAW on a stator transducer. The distribution generated fluctuating friction on the surface of SAW substrate. When the surface with burst SAW is explored by fingertip through a slider, the fluctuation can be transformed into vibration and perceived as tactile sensation at mechanoreceptors in our finger skin. A prototype of the SAW tactile display is fabricated according to the principle. Rubbing the substrate through the slider, we can feel tactile sensations under a control depending on the rubbing motion. A controller for the prototype is developed. For evaluation of slider steel ball vibration, steel ball velocity under the control is measured. Two sets of the control parameters are selected so that operators can discriminate two kinds of roughness sensation. Effectiveness of the selection is evaluated through an experiment with a large number of subjects.

    A vibration isolation system with weight support mechanism using zero-power control is presented in this paper. Zero-compliance to direct disturbance of the system can be achieved by connecting a normal spring in series with a spring of negative stiffness by zero-power control. To improve the performance of the system for direct disturbance, a weight support mechanism is introduced. In this research, analytical and experimental studies have been conducted to measure the effectiveness of the isolation system. It is showed that the system is capable to realize negative stiffness as well as to suppress the disturbances even using such additional mechanism.

    Surface acoustic wave (SAW) linear motor, which is a kind of ultrasonic motor, had many advantages such as high force, high speed and precise positioning. Relationship between motor speed and input voltage, however, had nonlinearity at lower speed due to its friction drive principle. Thus SAW linear motor could not obtain a stable drive at the low speed area. In this research, PWM (Pulse width modulation) was applied for controlling the slider speed. Lower speed in non-linearity area was realized. Furthermore precise positioning was also discussed.

    An active three-degree-of-freedom vibration isolator using zero-power magnetic suspension was developed to attenuate the effect of direct disturbances and to isolate vibrations transmitted from the ground. The zero-compliance of the isolator for direct disturbances was realized by connecting a conventional spring in series with an active suspension mechanism. In this research, analytical and experimental studies have been conducted to measure the effectiveness of the isolator under both types of disturbances. The transmissibility characteristics of the isolator from the floor showed that the vibration isolation performance could be improved by selecting suitable parameters of the zero-power controller and the damping between the base to middle table.

    This paper shows a control method which enables a suspension mechanism with an air actuator to have negative stiffness. An experimental apparatus is manufactured for experimental study, in which the table is suspended and drived by an air actuator. Applying the proposed control method to this apparatus, we have confirmed that the steady-state displacement of the table is in the direction opposite to load, that is, the system has negative stiffness.

The slider that has the smaller projections and uniform distribution of the projections exhibited higher performance. By using the optimized silicon slider, the motor was driven at the output force of 6.4 N. A larger silicon slider, which can perform larger output force, was also discussed, for a larger slider has larger contact area. When a silicon slider which is longer along SAW propagation is driven, dump of SAW due to driving the slider is observed.

    This paper describes the way of miniaturization of a surface acoustic wave(SAW)linear motor and characteristics of the miniaturized motor. A stator transducer can be miniaturized by operation at higher frequency. The miniaturized SAW linear motor could be successfully driven at the operating frequency of 50 MHz and 70 MHz. The limit of miniaturization, namely driving frequency limit, is also discussed. It seemsthat the limit depends on the surface roughness of the stator transducer.

  • 弾性表面波皮膚感覚ディスプレイ               
    2001年
    これまで、超音波のメカトロニクスへの応用に関する研究に従事してきた。弾性表面波という振動モードを用いて、センサやアクチュエータへの応用に関する研究を行った。アクチュエータの開発では、薄型の構成のリニアモータを実現することができた。現在では、弾性表面波の機械振動を利用して、人が固体表面をなぞったときの感覚を再現する装置の開発を行っており、バーチャルリアリティーやロボットなどの遠隔操作への応用を目指している。
