Estimation of Rate-Dependent Hammerstein Model of Piezo Bender Actuator

Abstract

The paper presents a Hammerstein model of a commercial piezoelectric bender PL140 from Physik Instru-mente Co. The model consists of a nonlinear static part that describes the inherent hysteresis and a linear dynamic part that is represented by the auto-regressive model with exogenous input. The linear model parameters are estimated one-time using a particle swarm optimization algorithm. The rate-dependent nonlinear part is identified using input voltage data, along with a hidden variable that is obtained with the help of the inverted linear part. The experimental data are generated by a PL140 Simscape model with parameters set in accordance with catalog data.
