Operator-based parallel compensation control for hysteresis using ELM-based stop-type PI model

In this paper, operator-based parallel compensation control for hysteresis is considered. In order to describe the hysteresis, play-type Prandtl-Ishlinskii (PI) hysteresis model is applied. By using properties between play and stop hysteresis operators, a parallel compensator is designed by stop-type PI hysteresis model which is constructed by using Extreme Learning Machine (ELM). As a result, the hysteresis dynamics is compensated. According to operator-based right coprirne factorization, 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.
