Abstract:

In view of the precise speed control of brushless DC motors,the article discusses the advantages of the combination of classic PID and modern fuzzy control,and simulates the motor speed controller by fuzzy PID control method.The result of online simulation shows that the fuzzy PID controller is better than the classic PID controller in response properties and anti-jamming performance.

Key words: fuzzy PID;speed control system;brushless DC motor;cascade control
