Abstract :
Permanent magnet synchronous motor (PMSM) is a high-order, nonlinear system with strong coupling. When the system parameters vary or disturbances occur, conventional linear regulation law can not satisfy the higher requirements with the speed-adjustable system. According to the sliding mode variable structure and the vector control theory, we design the sliding mode controllers (SMC) in the speed loop and the current loop based on double closed-loop system with PMSM, which solves the problem of the parameters change and disturbances in the system. The simulation results show that the scheme for the parameter variations of the system and disturbances has good rapidity and strong robustness.
