Brushless DC Motor Speed Fuzzy Adaptive Control System

Abstract

For brushless DC motor speed control accuracy is not high, this paper adapts adaptive fuzzy PID control method to control rotation speed and the current double speed closed-loop speed control systems, combine the fuzzy controller and the PID controller with adaptive factor, self-tuning control parameters online, and further improve the system of control precision. The simulation proved that using adaptive fuzzy PID control, the response speed and accuracy improve regulation, steady-state performance good, without super-harmonic oscillation.
