Model of Start-Stop Control on Low Speed Moving
This paper analyzes the cause of overshoot and retarded response in controlling piezoelectric ceramic motor with PMAC card in micro WEDM. The model of start-stop control is presented, and the servo control card with start-stop control is also developed. The model reserved the advantages of traditional PID control, and overcome the problems of overshoot and retarded response. It has been verified by machining that system overshoot is less than 3 pulses and response time is less than 1 second.
