Abstract

An optimized PID controller designed for piezoelectric actuator based on classical Bouc-Wen(BW) hysteresis model is proposed in this paper. Generally, hysteresis nonlinearity existing in the smart materials such as piezoelectric actuators can cause undesirable inaccuracy. In this paper, the classical BW hysteresis model is presented and parameters identification via the particle swarm optimization (PSO) approach for piezoelectric actuator is performed. For the purpose of obtaining a better tracking performance, the PSO method is adopted again to search for each parameter. The testing results validate that the optimized PID controller can enhance the PZT's tracking accuracy.
