This paper discusses the adaptation of the Preisach model to describe the h
ysteresis behavior of piezoceramic actuator system and presents a modified
geometric interpretation and numerical implementation method fur the Preisa
ch model especially fur the hysteresis modeling of piezoceramic actuator sy
stem. The demagnetized-state, which refers both input and output equal zero
state, and the generalized demagnetized-state are used as the basis of Pre
isach model rather the saturation states. Experiments on the hysteresis beh
avior of a piezoceramic actuator were carried out and the experimental meas
urements are compared with the hysteresis predictions. The comparison resul
ts verify the application of the modified Preisach model to piezoceramic ma
terial system.
