On the classical Preisach model for hysteresis in piezoceramic actuators

A classical Preisach model [Mathematical Models of Hysteresis, Springer, New York, 199 1] is developed using a piezoceramic actuator in a stacked form. The classical Preisach model is shown to offer excellent modeling accuracy when the actuator is not subject to any load and is subject to an excitation voltage signal at a low frequency. The accuracy of the Preisach model is shown to increasingly deteriorate as the load being applied to the piezoceramic actuator is increased or the range of frequencies contained in the voltage excitation signal gets wider. The classical Preisach model remains, though, a good model for hysteresis in piezoceramic actuators in applications where the load fluctuation is relatively small and the range of frequencies of the voltage excitation is limited.
