Design of Multi-motor Synchronous Control System

Abstract

Aiming at the problem of multi-motor synchronous control in engineering projects, a multi-motor synchronous control system is designed. The system takes multiple permanent magnet synchronous motors as the control object, and adopts the deviation coupling structure in multi-motor synchronous control. Aiming at some problems in the permanent magnet synchronous motor and the deviation coupling structure, a model based predictive control and BP neural Deviation coupling control structure combined with network PID. The Matlab/Simulink simulation platform is used to simulate the designed control structure. The simulation results show that the designed multi-motor synchronous control system has fast adjustment time, small overshoot and strong anti-disturbance. Compared with the traditional control scheme, the effect is improved obviously, and the synchronous control can be better realized.
