Abstract :
In this paper, the generalized Bouc-Wen model is used to model the hysteresis nonlinearity of a Giant Magnetostrictive Actuator (GMA) and the model´s validity is verified by experimental data. Based on this model, a feedforward controller based on hysteresis observer is used to compensate the hysteresis nonlinearity. A first-order process feedback strategy combined with the feedforward compensation is proposed to eliminate the model error. Numerical simulation shows that the control method is effective.
