Abstract

The hysteresis characteristic of piezoelectric actuator seriously affects its tracking precision, even leads to instability of the closed-loop control system. To solve this issue, this paper employs the classical Preisach model to describe the hysteresis characteristic of piezoelectric actuator, and then compensates for the hysteresis by using inverse Preisach model. Moreover, a new fuzzy PID controller is designed to realize a fuzzy feedback control system of the piezoelectric actuator with inverse-based feedforward compensation. Simulation investigations show that fuzzy PID control achieves significant improvements in terms of response time, overshoot, and steady-state error as compared with traditional PID control. In addition, some open problem which is still need to be solved in the control of piezoelectric actuator and its future development are also discussed.
