摘　　要：通过转矩角增量和定转子磁链的位置,计算出补偿转矩和定子磁链的参考电压矢量,利用空间矢量调制技术实现对逆变器电压状态的控制,改善了系统的性能。给出了仿真结果,证明了算法的合理性和有效性。Based on the relationship between the torque angle and motor speed, the reference voltage vector is calculated, and the switch signals of the inverter is generated by SVM technique. Simulation results show that this system can effectively reduce the ripples of motor torque and stator flux, and also prove the rationality and validity of the algorithm.
