Abstract

In this paper, a Hammerstein model with Preisach operator is proposed to model the rate-dependent hysteresis nonlinearity of a Giant Magnetostrictive Actuator (GMA). The Preisach operator is used to represent the nonlinear block of this model. The model´s validity is verified by experimental data. Based on this model, a PID feedback controller combined with an inverse compensation in the feed-forward loop is proposed for tracking control. Experimental results show that the control method is effective.
