In view of the influence of interference on permanent magnet synchronous motor control system,an improved faln function based active disturbance rejection control for permanent magnet synchronous motor was proposed.An active disturbance rejection controller of permanent magnet synchronous motor is designed.By analyzing the influence of fal function on the active disturbance rejection controller,an improved faln function with limiting amplitude is proposed,and then an extended state observer is designed.The experiment results show that the improved faln function based on permanent magnet synchronous motor auto-rejection control method has better anti-interference performance than the traditional auto-rejection control.
