Based on the analysis of permanent magnet brushless DC motor mathematical model and fuzzy control algorithm, the permanent magnet brushless DC motor control system simulation models were built using MATLAB, including brushless DC motor, fuzzy PID controller and a phase module.Digital dual loop control was applied. PI control was used in the inner current loop, and fuzzy PID controller was used in the outer ring of the speed loop. Simulation parameters and motor rated speed were set, and the control system simulation was achieved. The results show that the designed control system possesses rapid response speed, good stability. Fuzzy PID control algorithm is ideal for system control strategy of mining permanent magnet brushless DC motor control.
