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.
