ABSTRACT

Firstly, this article establishes the mathematical models and speed principles of brushless DC motors. Next, it designs fuzzy PID controllers and current adjustors based on the adjusting speed theory and characteristics of brushless DC motors, which form double closed-loops to achieve intellectualized adjustment of brushless DC motors, creating the best effects simultaneously.

Keywords:

Brushless DC motor, fuzzy PID controller, speed control.
