【Abstract】 An ultrasonic motor(USM)is a new type of motor,and the method of driving and control of USM is different from traditional electromagnetic motors.A DSP-based Control System For Ultrasonic Motors is mainly concentrated on In this paper. This control system can operate three control methods at the same time,which are voltage control,frequency control and phase-difference control. The techniques of the hardware and software of this system are respectively introduced. Finally, the stability of this control system is demonstrated by experiments.更多还原
