Active Disturbance Rejection Control for Permanent Magnet Linear Synchronous Motor

Considering internal parameters variation and external disturbance will greatly affect the performance of permanent magnet linear synchronous motor (PMLSM) control system, the active disturbance rejection control (ADRC) strategy is studied in this paper to enhance the anti-disturbance ability and dynamic performance of the system. Compared with the traditional PI control, ADRC has smaller overshoot, better adaptability, greater robustness to parameters variation and stronger anti-interference ability. The corresponding Simulink model is set up and its Simulink results are analyzed to prove the above advantages.
