Control of Ultrasonic Motor Based on Dsp
نویسندگان
چکیده
Considering the special working principle of USM (ultrasonic motor), we selected a drive voltage which was taken as the controlling variable to regulate its speed. In this paper, we improved the traditional PID control into incremental PID control. In order to realize the speed control of USM, a controller based on DSP2812 was designed. Applying sine signals of different frequencies through the experiment, we’ll find that the developed control scheme was highly effective, reliable and applicable for the ultrasonic motor.
