In this paper,the mechanical synchronous transmission mode of industrial sewing machine is discussed,and a multi-motor synchronous control system is introduced.This paper analyzes several common multimotor synchronous control methods,combined with good synchronous performance of bias coupling control,designs and sets up the experimental platform of three-motor synchronous control system based on DSP,completes the programming design of three-motor synchronous control system and completes the verification experiment of multi-motor synchronous control algorithm.Experimental results show that the system can improve the synchronization performance and meet the requirements of the controlled object for high precision synchronization control.
