Hysteresis is a fundamental problem in most smart material-based actuators. This phenomenon limits the performance of systems driven by these actuators. This paper presents a control fusion strategy for hysteretic piezoelectric-based actuators which are described by Bouc-Wen model. A discrete prescribed performance control algorithm is developed and fused into the BW model. To verify the effectiveness of the modelling and control methods,experiments are made on a commercial piezoelectric actuator product. It is shown that the proposed controller guarantees not only the asymptotic stability but also transient performance.
