Abstract
Based on errors of torque and stator flux, the reference voltage vector was determined by the principle that the error is zero during one periodic time; then the voltage vector can be composed by using Space Vector Pulse Width Modulation (SVPWM). Because the magnitude and direction of output voltage vector is arbitrary in this method, it is able to track the setting value of torque and flux linkage primely, the voltage and error of flux linkage at the time of sampling can be offset in the next period, so that the pulsation of torque and flux linkage is reduced effectively. Through imitation and experiment, it was proved that this control strategy is correct and effective.
