Sliding mode control of high-speed PMSM based on precision linearization control

To improve dynamic quality of High-Speed PMSM control system, a novel design method for velocity and current loops was proposed. In the novel method, sliding mode variable structure and precision linearization strategies were applied to achieve decoupling control. Integrated speed and current sliding mode Controllers was designed. Simulation and experimental results show that the proposed method can improve steady, dynamic performances and robustness characteristics of control system validly.
