Abstract

With the technological development of the society, permanent magnet synchronous motors are used more and more widely, especially in the two-motor synchronous system. Aiming at the problems of response performance and anti-interference ability of the dual motor synchronous system, this paper proposes an improved sliding mode speed control controller. First, its mathematical model is established by analyzing the mechanical principle and working principle of the permanent magnet synchronous motor. On the basis of the traditional sliding mode controller, the sliding mode surface and convergence rate are improved to obtain the improved sliding mode controller, and the simulation model of the improved sliding mode controller is built. MATLAB/Simulink is used to build a dual motor synchronous system model for verification, and the experimental results show that the improved sliding mode speed controller has no overshooting, fast response speed, and strong anti-jamming ability, and its response performance and anti-jamming ability are better than that of the traditional sliding mode speed controller.
