This article analyses the structure and working principle of the brushless DC motor, the advantages and disadvantages of PID regulation and fuzzy control are analysed as well, and puts forward the fuzzy PID motor control technology with both advantages. The speed control of the brushless DC motor is carried out and the simulation model is built. The results show that, compared with the traditional PID adjustment, the fuzzy PID makes the motor speed more stable and the speed fluctuation decreases obviously, which satisfies the requirement of the speed control of the electric bicycle.
