Synchronous Control Theory and Practical Study of Multi-motor Synchronous Driving System

Abstract

The multi-motor synchronous driving control system exists generally in industrial production. This paper surveys the newest achievements in this subject in recent years, and puts forward a multi-motor synchronous driving control system based on compensation theory and Internal Model Control (IMC). This system can eliminate overspeeding as well as keeping fine disturbance rejection ability, so that better following performance and synchronous precision is attained, which is proved by simulation results. The future development is pointed out in the end.
