Повний текст джерелаCurrently, systems integrate more and more functionalities into smaller volumes thanks to embedded micro-components. The assembly of those components requires precise and repeatable systems of manipulation. Substantial amounts of research have been carried out for developing actuators and microrobots to perform positioning or manipulation with micron- or even submicron accuracies. Piezoelectric technologies play a fundamental role in positioning applications with nanoscale or even lower resolution. These materials make possible the design and development of positioning systems with high resolution and bandwidth. However, nonlinear effects such as hysteresis and creep affect the position accuracy of piezoelectric-based systems if not controlled. Often, position sensors are mounted to these systems to permit a feedback control and the elimination of the hysteresis and creep effects. Nonetheless, the integration of sensors to enable quality and robust servo control poses specific problems for microrobots. This is especially true when the number of degrees of freedom (DOF) increases. Precision position sensors are usually very bulky and expensive. Alternative solutions to the integration of external position sensors can be grouped into two categories: either by open-loop control, also called feedforward control schemes or by Self-Sensing Actuation (SSA) control-based techniques, that is, a feedback control that uses the piezoelectric actuator as its own sensor.In this thesis, the objective is to design and control a piezoelectric-based positioning system with an embedded measurement by SSA method and having several degrees of freedom. To this end, the two classes of SSA, namely SSA based on the piezoelectric direct effect and the SSA based on the change of electrical properties of the piezoelectric actuator (PEAs), are studied in depth to determine the more adequate for force and position control in piezoelectric actuators typified by creep and hysteresis nonlinearities and devoted to precise operations. Additionally, from this study, an improved constitutive model and parameter identification technique are presented which includes the electromechanical coupling effect on the piezoelectric material properties (elastic and dielectric constants).A novel technique for real-time evaluation of the PEA's electrical properties is developed. This evaluation is based on the measurement of the amplitude of the detection current that results from the application of high-frequency low amplitude input voltage that is superimposed to the control input voltage which actuates the PEA. Then an estimator that uses the detection current to estimate the PEA's position is designed. Finally, a microrobotics platform for planar positioning with high resolution and the developed embedded measurement by SSA is presented

In this study, the three degrees of freedom mechanical arm actuated by six pneumatic muscle actuators is used as a rehabilitation robot. It is difficult to achieve high control accuracy using classical control method, because the compressibility of gas and the nonlinear elasticity of bladder container caused parameter variation. We use two intelligent controllers to implement angle control and end-effector tracking control. The linguistic approach learning mechanism is used to modify on-line fuzzy rules and the fuzzy sliding surface can reduce fuzzy sets. And then the adaptive law is used to adjust scaling factor. The experimental results show that adaptive self-organizing fuzzy sliding mode controller can attain excellently tracking control performance .

Generally, actuator can be classified as two forms, one is piezoelectric actuator, and the other is electromagnetic actuator. Moreover, standing wave type and traveling wave type are two major types of piezoelectric actuators. In this paper, converse piezoelectric effect occurs as we input voltage and driving frequency in piezoelectric plate. Piezoelectric effect is a phenomenon about mechanical energy transformation. We excite electrode to generate ultrasonic vibration that cause rotor to drive in elliptical motion and make stator start to move. The purpose of this study is using standing wave type method to drive stator. The three piezoelectric actuators are attached to the foundation of fixture above the base that arrange asymmetrically and separate in 120 degrees. Besides, we can adjust the distance of fixture based on the size of rotor. The powerful magnet below the center is to increase the weight of stator by means of magnet suction. To increase the efficiency of piezoelectric plate, we must find the location of the fixture and the friction elements on the piezoelectric ceramic chaps by using finite element analysis software. The optimal driving frequency in mode(1,0), mode(0,1)and mode(1,1) is 194 frequency, 195 frequency and 191 frequency. The structure of the two degrees of freedom piezoelectric actuators consist of three asymmetrical ceramic chaps, fixtures, friction elements, foundation of fixture, acrylic base, and rotor. There are three major situations about driving modes. In the first driving mode(1,0), the rotor applies a clockwise rotation around the y – axis with the highest speed as 54.2rpm. In the second driving mode(0,1), the rotor applies a anticlockwise rotation around the y – axis with the highest speed as 40.1 rpm. In the third driving mode(1,1), the rotor rotate around the x – axis with the highest speed as 26.6 rpm.

In this paper, precision tracking control of Five-Degrees-of-Freedom piezoelectric-actuated systems is discussed. Generally, the piezoelectric-actuated system can be modeled as a linear model coupled with a hysteresis. In order to obtain precision tracking control, Prandtl-Ishlinskii (PI) model is used to model the hysteresis nonlinearity. Then, the inverse PI model is used to reduce the hysteresis nonlinearity and a sliding-model controller is designed to compensate the remaing nonlinear uncertainty and disturbances. After the linear model is identified a sliding-mode controller can be designed for the motion control of a nano-stage. The experimental results presented to verify the usefulness of this method.

In recent years, Automatic Optical Inspection (AOI) plays an important role on modern semiconductor and optical industries. A typical AOI equipment consists of a camera mounted on a gantry for performing large-area inspection. Fast and accurate movement would influence the inspection efficiency. However, the motion induced vibration during fast transition could significantly increase the settling time and therefore deteriorate the inspection rate. In this thesis, a piezoelectric driven compliant stage was design as the carrier for camera. By integrating control scheme with the stage, it is possible to suppress the vibration and therefore improve the performance of AOI. The objective of this research is to develop a PC-based closed loop X-Y axes micro-nano positioning system. The developed system mainly consists of two piezoelectric actuators, two displacement magnification mechanism, the micro-nano positioning stage analyzed by the FEM software -ABAQUS, piezo amplifier, two capacitive sensors, and a PC. The structure of the positioning stage has been designed as stacked serial type. A lever for displacement magnification mechanism has been used to enlarge the travel of each PZT actuator. The movement of the designed micro-nano positioning stage body was constrained by four sets of flexible hinge cut by wire electrical discharge machining.The geometric dimensions of the hinge have been determined by executing the optimization function using the ABAQUS software on static and dynamic analysis. Based on the test results, the designed stage have good performance in fix-point control and dynamic tracking. This study has successfully set up a positioning system. Its characteristic is simple structure with low cost and low-needed of hardware equipment. This positioning system can achieve high-precise motion. It is hope that the result of this study can be expanded to longer stroke and higher precise positioning system, and integrates every mature technology to develop more superior precise instrument in the future.
