Abstract: In order to describe the hysteresis, play-type Prandtl-Ishlinskii (PI) hysteresis model is applied in this paper. For compensating the effect of hysteresis which precedes plants, an extreme learning machine (ELM)-based parallel compensator is designed by using properties between play and stop hysteresis operators. Based on the compensated plants, according to operator-based right coprime factorisation, a feedback controller and a tracking controller are designed to guarantee the output tracking performance. Finally, the numerical simulation results are presented to validate the effectiveness of the proposed method.
