Abstract: In this paper, the mathematical model of BLDCM drive system using current inverter has been analyzed. On the basis of the state equation of system, the simulation program was complied in the Matlab software, then, the method about how to choose parameter in the simulation system was introduced in detail. In the simulation, the PI closed loop control strategy that was used to the motor was successfully implemented, and the four-quadrant operation of the current inverter was also simulated. So the result of the simulation provided important reference for the real system.
