| Abstract: | Based on the weakness of traditional PMSM Vector Control in dealing with sudden load disturbance,a new method of load torque feedforward compensation current loop control was proposed in this paper.In order to detect the load of the motor in real time,this paper designed a Luenberger load torque state observer,which optimized the current loop in the form of the detected load torque feedforward compensation,improved the anti-load ability of PMSM vector control system,and realized the optimization of dynamic and steady characteristics.Finally,the control system model was built by Simulink and simulation was carried out to verify the feasibility of the method. |
