fuzzy PID controller for piezoelectric actuator system

The system is a non-linear system, bouc-wen model used to describe the hysteresis behavior of the actuator, this hysteresis nonlinearity of PZA actuator deteriorate and limit the system tracking performance and error. my objective : I want to design PID controller using zigler-nichols method tuning for the system and then design fuzzyPID controller for the non-linear system to enhance the performance of the system and evaluate and compare the performance between fuzzy PID and PID controller, and fuzzy PID controller should have the best performance than PID, the result show by normal scope and graph scope , also the input use sinusoidal and step input .
