The Application of Self-adaptive Fuzzy-PID Control to Speed Regulating System of BLDCM

The simulative modules of speed regulating system of BLDCM were built based on the mathematical model. The transfer function of the rotating speed was obtained. The fuzzy PID parameters of self-adaptive controller were introduced. The function of PID controller was improved according to both the error and the variety rate. The simulative results show that self-adaptive Fuzzy-PID Control has faster dynamic response and smaller overshoot compared with traditional controller.
