A position control scheme for an ultrasonic motor using an adaptive controller with dead-zone compensation is presented in this paper. In the proposed controller, the adaptive control scheme compensates the time-varying characteristic of the motor with online parameter identification. In order to overcome the effect of a dead-zone, a P controller is adopted. The effectiveness of the proposed co...
