Research of control algorithm of active disturbance rejection for permanent magnet linear synchronous motor

For characteristics of permanent magnet linear synchronous motor that it is sensitive to external disturbance and parameter variation,an improved active disturbance rejection control algorithm was proposed based on traditional active disturbance rejection technique and in combination with feedforward and feedback control.Using the improved active disturbance rejection control algorithm can effectively observe and compensate dynamic coupling disturbance in speed and position control system of permanent magnet linear synchronous motor.The simulation results show that the improved algorithm has better dynamic and static performance than classical PID and traditional active disturbance rejection control algorithm.
