Abstract

Many of the smart materials being investigated (e.g., piezoceramics, shape memory alloys (SMAs), and magnetostrictives) exhibit significant hysteresis effects, especially when driven with large control signals. Furthermore a single input single output hysteresis model may not adequately capture the corresponding nonlinear effects due to the influence of an unmodeled parameter, and two input hysteresis models may therefore be more appropriate. In this paper the Preisach model and inverse compensator for a piezoceramic sheet actuator is described and experimental data presented. The effect of a large independent applied stress on the observed applied electric field to measured strain hysteresis for a piezoceramic sheet actuator is demonstrated.
