摘要：
A novel anti-disturbance control for permanent magnetic Synchronous Motor(PMSM) based on reduced order load torque observer is proposed to solve the speed ripple problem caused by the external uncertainties like load torque disturbance and parameter variation. Combined with the vector control, the estimation value of the reduced-order torque observer is used as compensation to the q-axis current to improve the dynamic response of the speed. The accuracy of the inertia estimation, the rationality of the reduced order load torque observer and the optimization of the system are verified by the simulation result.
