摘　　要：针对内置式永磁同步电机(IPMSM)d,q轴电流存在动态耦合的问题,在此基于有效磁链概念得到了IPMSM的复矢量数学模型,设计了相应的复矢量电流调节器,实现了d,q轴电流的动态解耦。相比于状态反馈解耦控制,复矢量解耦控制具有更好的动态解耦效果,并且在一定程度上提高了电流环控制系统的参数鲁棒性。仿真和实验结果验证了所提方法的有效性和可行性。Aiming at the problem of d,q axis current dynamic decoupling in the vector control of interior permanent magnet synchronous motor(IPMSM),the complex vector mathematical model of IPMSM is obtained based on the concept of effective flux linkage,and the corresponding complex vector current regulator is designed to realize the dynamic decoupling of d,q axis current.Compared with state feedback decoupling control,the complex vector decoupling control has better dynamic decoupling effect and improves the parameters robustness of the current loop control system to a certain extent.Simulation and experimental results verify the feasibility and effectiveness of the proposed method.
