Abstract Permanent magnet synchronous motor is a complicated system with a nonlinear, strongcoupling and multi-variable. By using method of the rotor field oriented vector control, the couplingproblem is solved between the exciting and torque current for permanent magnet synchronous motorvector control, but cannot eliminate the decreasing of the current control accuracy and poor dynamicperformance to the dynamic coupling between d, q axis voltage for the model essentially, thus, currentfeedback 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 decouplingcontrol methods.
