Abstract:
Stator flux linkage and torque ripple are large in traditional direct torque control(DTC)of permanent magnet synchronous motor because of the Hysteresis Control.Space vector modulation(SVM)is based on the precise compensation of the error of stator flux linkage and torque,so it is effective to reduce the ripple.However,two PI regulators are included in traditional SVM method,one is speed regulator and the other is torque regulator.Design of Parameters of the two PI regulators is complex and the motor performance is effected by these Parameters directly.The paper embarks from the nature that DTC control torque angle and presents an improved method of SVM.The motor can be controlled efficiently through dynamically adjusting the output limit value of torque angle regulator.Complex debugging process of the PI parameters can be eliminated in this method.The correctness and validity of the proposed method are verified by simulation result.
