Permanent magnet synchronous motor (PMSM) has been widely used in industrial fields. The conventional control method for vector control of PMSM is PID, which has some disadvantages such as large overshoot, bad robustness. In this paper, a cascade control strategy with three rst-order linear active disturbance rejection controllers( LADRC) is proposed, which can achieve not only cascade control of speed and q- axis current but also decoupling of d- axis and q- axis current. In order to improve the anti-disturbance ability, a load disturbance observer(LDO) is designed for model compensation. The simulation results show that, compared with PI controller , cascade LADRC method with model compensation has advantages of no overshoot, strong robustness and anti-disturbance ability.
