Through modular and integrated design, a prototype model of the BLDC controller was trial-manufactured and a C lan- guage programming was applied into the speed loop fuzzy control and current loop PI control algorithm. A BLDCM speed regulating system test platform was built. The results showed that the BLDCM control system has advantages of fast response and little overshoot, which can ensure its excellent static and dynamic performance.
