Abstract：Dual-winding permanent magnet synchronous motor (PMSM) can improve the operating range by reconfiguring the windings of the series and parallel modes. However, the motor parameters variation in different winding modes could cause the traditional PI controller to be unable to satisfy the high-quality operation requirements. According to the operating characteristics of this type of motor, this paper studies a composite sliding mode variable structure controller that integrates speed loop control and anti-disturbance observation, which could effectively suppress the dynamic fluctuation of speed caused by motor parameter variation and winding reconstruction. Firstly, the working mechanism of the dual-winding PMSM in different modes and the reasons for the speed fluctuation during winding reconstruction are analyzed. Secondly, a sliding mode variable structure controller is designed to realize the self-adaptation of control parameters and quickly meet the reconstruction of the instantaneous current relationship to suppress dynamic fluctuations. Finally, a comparative experiment is carried out under typical working conditions for the scheme using PI controller and the sliding mode variable structure controller through a miniature principle prototype, which verifies the effectiveness and feasibility of the proposed control strategies.
