| Abstract: | The Prandtl-lshlinskii model expressed by play and stop operators is used to describe the unknown hysteresis, which is convenient for controller design. For the continuous-time linear dynamic control systems in state space form preceded by the unknown hysteresis, a model reference adaptive control approach is proposed. This adaptive control law ensures global stability of the closed-loop system and the tracking with a desired precision. The undesirable inaccuracies and oscillations caused by the unknown hysteresis can be mitigated effectively. The effectiveness of the proposed method is demonstrated through a simulation example. |
