Research on the Model of the Magnetostrictive Actuator
One of the characteristics not to be ignored of the magnetostrictive material used in active vibration control is its hysteresis. In this paper this characteristic has been studied. At first a mathematical model of the hysteresis loop has been obtained on the basis of experiment. This model depends on the frequency and the amplitude of the alternating current inputted to magnetostrictive actuator. Then further modeling of the magnetostrictive actuator has been put forward.
