摘　　要：针对转子磁链定向的传统矢量控制系统解耦性能差的问题,提出一种定子磁链定向的控制方法.该方法通过设计磁链调节器和转矩调节器,添加去耦项来提高磁链和转矩的解耦效果;利用电压模型观测定子磁链,避开了转子参数的影响.结果证明,定子磁链观测准确,磁链和转矩的解耦效果良好.通过仿真和实验证明了该方法的有效性.As the traditional rotor flux oriented control has poor decoupling performance, stator flux oriented control is proposed. In this method, the decoupling effect of flux and torque is improved by designing flux linkage regulator and torque regulator and adding decoupling terms the stator flux is observed by using the voltage model, and the influence of the rotor pa- rameters is avoided. The results show that the stator flux observation is accurate, and the de- coupling effect of flux and torque is good . The effectiveness of the method is proved by the simulation and experiment.
