Abstract:

For the shortcoming of big error for open-loop control and bad dynamic and static characteristics for single-closed loop control, the double-closed loop control system is studied for Permanent magnet. Firstly the paper introduces the working principle of PWM speed regulation for PMBLDCM, and then expounds the design process of the double closed-loop control system, and inferences the mathematical model of the current regulator and speed regulator in detail. Finally, the simulation results validate the double closed-loop control system of PMBLDCM has good dynamic and static characteristics.
