In order to model the hysteretic curve between the displacement and applied voltage from and to the WTYD type piezoceramic micro-actuators

the Bouc-Wen model to characterize the hysteretic relationship between the displacement and applied voltage from and to the piezoceramic micro-actuators is put forward through using the Bouc-Wen hysteretic operator to mimic the hysteretic component and a corresponding parameter identification method is established. In order to evaluate the effectiveness of the developed model and parameter identification method

the corresponding experimental setup is established and the model validation is carried out. The research results show that the proposed Bouc-Wen model for the WTYD type piezoceramic micro-actuators and the parameter identification method can portray the hysteretic characteristics of the WTYD type piezoceramic micro-actuators.
