Position Synchronous Timing Control Method of Multiple Permanent Magnet Servo Motors System

Abstract— With the needs of production and life and the development of science and technology, Multiple permanent magnet servo motors (MPMSMs) system has been widely used in Computer Numerical Control (CNC) machine tools and intelligent robots. Since the traditional MPMSMs control cannot make the system converge the motor position angle to the desired position within the specified time, this paper designs the Position Synchronous Timing Control method of MPMSMs System. At the same time, the current controller introduces the deadbeat current predictive control. Since there is a one-beat delay between the actual digital system and the control algorithm, the deadbeat current predictive control is compensated by one beat. Compared with the traditional proportional integral (PI) controller, the position synchronization timing control of the MPMSMs system based on Terminal sliding mode control can realize the timing synchronization control of the MPMSM system, and improve the steady-state accuracy and dynamic response of the system.

Index Terms— multiple permanent magnet servo motor, permanent magnet synchronous motor, sliding mode control, current predictive control, synchronous timing.
