A suitable driving circuit is very important for the operation of traveling-wave ultrasonic motor(USM),whether the design of the driving and control circuit is reasonable or not will be closely correlated with the performance of the motor system.On the other hand,the appropriate closed loop control of USM is a necessary condition for avoiding weaknesses and giving full play of the ultrasonic motor.This paper describes some topological structures of the driving circuit which includes push-pull,H-bridge and so on, analyzes the structure of DSP-based driving and control circuit.Then,the control characteristics of ultrasonic motor are summarized,a variety of suitable strategies for the control of ultrasonic motor are also presented in this paper.
