摘　　要：永磁同步电机是一个非线性、强耦合、多变量的复杂对象,转子磁场定向的矢量控制方法解决了永磁同步电机控制中励磁与转矩电流之间的耦合问题,但矢量控制无法消除永磁同步电机模型本质上存在d、q轴电压之间的动态耦合造成电流控制精度降低,动态性能变差的问题。对此,提出了电流反馈解耦和偏差解耦两种解耦控制方法,分析了各自的特性,并用Simulink搭建了仿真模型,仿真结果验证了解耦控制方法的有效性。Permanent magnet synchronous motor is a complicated system with a nonlinear, strong coupling and multi-variable. By using method of the rotor field oriented vector control, the coupling problem is solved between the exciting and torque current for permanent magnet synchronous motor vector control, but cannot eliminate the decreasing of the current control accuracy and poor dynamic performance to the dynamic coupling between d, q axis voltage for the model essentially, thus, current feedback decoupling and deviation decoupling method are proposed, and the characteristics are analyzed, a simulation model is build with Simulink, simulation results show the effectiveness of the decoupling control methods.
