Abstract :
Dynamics of magnetostrictive actuators exhibit hysteresis, which must be incorporated in control design. Finite element method model defined in terms of magnetic vector potential combined with magnetic hysteresis model is proposed to describe underlying phenomena. Closed loop control is coupled to the actuator model. The performance of a linear controller is studied.
