Dynamic Modeling and Control of Piezoelectric Ceramic Actuators Based on Improved Duhem

In order to solve the problem of hysteresis nonlinearity in the operation of piezoelectric ceramic actuator system, a rate dependent dynamic hysteresis nonlinear model based on the improved Duhem is proposed. At the same time, based on this model, an internal mode control method based on hysteresis linearization is designed. Finally an experimental platform is built for the control system to conduct experimental research. The results show that the control scheme can effectively solve the problems of the system and the control system achieve good control effect.
