The method is advantaged in that the method is suitable for a dual-motor synchronous control system.

Description

technical field [0001] The present invention relates to the technical field of electromechanical control, in particular to a dual-motor synchronous control device and method, which can be mainly used in the scene of high-precision dual-motor synchronous control. Background technique [0002] Dual-motor synchronous control technology means that the control system can control the operation of two motors at the same time, monitor the running state of the motors during operation, and feed back the synchronization error of the two motors to the control system in real time for synchronization error compensation. Through synchronous control The controller minimizes the synchronization error between the two motors and improves the control accuracy. Motor synchronous control has been widely used in manufacturing and production process automation control systems. The performance of synchronous control between motors directly affects the reliability and control accuracy of the system. ...
