Modeling and Analyzing Bouc-Wen Hysteresis Model

This paper focus on relationship between the model parameters and the hysteresis loop of Bouc-Wen hysteresis (BW), we will model and analyze the (BW) model for Piezoelectric Ceramic Actuators (PCA) with the effect of each model parameters on hysteresis loop. The poor knowledge of the effect of these parameters of hysteresis loop justify the weak use of this model. We study also the overall nonlinear actuator model and use Particle Swarm optimization (PSO) to obtain parameters of PID controller to have a linear model equivalent to the overall nonlinear actuator model. Simulation results performed on the nonlinear system verify the efficiency of the proposed method.
