Abstract: This paper presents a modified Preisach model to describe the nonlinear hysteresis property of Macro Fiber Composite (MFC). In order to apply the proposed model, two necessary and sufficient inherent properties which exist in most piezoelectric materials should be met, which are referred to as the wiped-out and the congruency. By using the hysteresis properties and the identified database, the numerical expressions of the proposed modified Preisach model are presented for different inputs in detail. Then several waveforms of input excitation schemes are experimentally realized in order to demonstrate the effectiveness of the modified Preisach model. The good agreement between the measured and predicted results show that the modified Preisach model is an effective mean for predicting the hysteresis of the MFC actuator system.

Keywords: Macro fiber composite (MFC), dynamics characteristics, electro-mechanical behavior, hysteresis property, modified Preisach model
