It has high requirement for the stability of permanent magnet motor coupler in electromagnetic coupler vector control,and the common vector control is difficult to meet the requirement which is need to be optimized. A multi objective particle swarm optimization of permanent magnet synchronous motor vector control optimization algorithm was put forward based on the design of the electromagnetic coupler and inductive power transfer circuit. The constraint model of control parameters was constructed,using the weight coefficients in the control objective function to control the importance in different target,thereby the multi-objective particle swarm optimization objective function was gotten,and the optimization of vector control was realized. Simulation results show that,using the vector control method for permanent magnet synchronous motor optimization design,it can improve the calculation accuracy of leakage inductance and excitation inductance of permanent magnet synchronous motor,and optimize power transmission efficiency of the motor. The electromagnetic coupler can realize stable voltage output in a wide load range and has high application value.
