Real-time compensation of hysteresis in piezoelectric-stack actuator tracking a stochastic reference

This paper presents a convenient way to invert the classical Preisach model to compensate the hysteresis of a piezoelectric stack actuator in real-time. The advantage of the proposed method lies in the possibility to track a stochastic signal and compensate the hysteresis in real-time. Experimental results show a reduction of the RMS tracking error by 67 % to 90 % by using the compensation algorithm designed.
