A simple model of hysteresis for smart actuators

Abstract

A novel phenomenal model for hysteresis in smart actuators is proposed in this paper. One of the features of this model is that it does not include any basis functions. Hence, it has much simpler structure than the well known Preisach model, KP model and PI model. Another feature of this model is that it does not rely on any differential variables. Thus, it does not need to solve differential equations. The properties of the model are discussed. Then, the methods to determine the coefficients of the model are presented. In this paper, the proposed model is applied to modeling of hysteresis in a piezoceramic actuator. The experiments of modeling procedure are implemented to validate the performance of the model.
