摘　　要：矢量控制系统在三相异步电动机中应用时,为了达到精准观测定子磁链,引入混合磁链观测器实现电流与电压模型磁链观测器有效结合。详细阐述电压磁链观测器与电流磁链观测器的原理,扬长避短将两者结合,深入细致地对混合模型磁链观测器进行了理论分析,并通过仿真和实验,验证了混合模型磁链观测器在异步电动机矢量控制系统中的可行性和优越性。When the vector control system is applied in 3-phase asynchronous motor,in order to achieve the accurate observation of stator flux linkage,a mixed flux observer was used to realize the effective combination of current and voltage model flux observer. The principle of voltage and current flux observer was described,and these two models were combined. The mixed model flux observer was analyzed by means of simulation and experiments. The feasibility and superiority of the mixed model flux observer in the vector control system of induction motor is verified.
