Electromagnetic coupler of permanent magnet brushless DC motor is an important device to achieve inductive power transmission. By optimizing the control design of electromagnetic coupler the stability and output gain of the electromagnetic coupler may be improved.This article sets forth a method to optimize the control of electromagnetic coupler based on particle swarm optimization. In the first it requires to design the equivalent circuit for electromagnetic coupler of the permanent magnet brushless DC motor in order to build parameter model to constrain the control of the electromagnetic coupler which takes the output voltage gain,power consumption and efficiency as the constrain parameter to build function for the control target and achieve improved control algorithm,so that the optimal design of electromagnetic coupler of permanent magnet brushless DC motor could be realized. Simulation results show that the design method for control of the electromagnetic coupler can effectively improve the output stability of the electromagnetic coupler of the permanent magnet brushless DC motor while the current gain,voltage gain and output efficiency of the motor is higher than that of traditional methods. It should demonstrates a sound value for applications.
