can any one help me how to model (matlab code) hysteresis non linearity of piezoelectric actuators to use in real time appliations

I am trying to control the displacement of piezoelectric actuator, for positioning applications. In order to compensate the hysteresis and creep non linearities (with small frequency of operation within 20 hz) I have to model the rate independent hysteresis. many hysteresis models are available in the literature like Preisach model , Maxwell slip model , PI model and so on. which model can i go for to use in real time application? (Matlab Code) Thank u..

hello madam

sorry to tell u that i m not giving solution to your question. But i have also the same doubt regarding hysteresis modeling of piezoactuators using matlab. i have also gone through various models like preisach, bouq wen etc. but i m trying to plot hystersis and model it using matlab code. myself divijesh working as a faculty come research scholar in nmamit, nitte. It will be greatful madam if v discuss the issue.i have also not got any answer. can u plz give ur mail id. my mail id is [e-mail].

thank you
