Analysis of Electromechanical Dynamics of a Piezoelectric Servo-device

To address the light-beam stability problem in a mechanical vibration environment, an electromechanical piezoelectric servo-device and its corresponding model based on the theory of piezoelectric ceramic and vibration mechanics are proposed in this paper. System simulation and numerical analysis are given in detail for the follow-up problem of the tactic of combined control. The simulation results show that the above system can effectively control displacement and has several advantages such as high precision, rapid response, wide bandwidth. The restrictions on the displacement and force in the design of device are pointed out.
