[Abstract]:Permanent magnet brushless DC motor occupies an important position in the current market, and the research of its system controller is of great economic value. Researchers have never stopped the research on this subject. The performance advantage of brushless DC motor is obvious in all kinds of motors. According to the mathematical model of brushless DC motor and its control theory algorithm, the simulation model of control system based on Matlab/Simulink platform is established and the simulation results are obtained. Combined with fuzzy control theory, the design of speed fuzzy Pi controller is completed, and an effective suppression method is proposed to solve the commutation torque ripple problem of brushless DC motor. Combined with the performance index of the control system, the overall scheme of the system is determined, the hardware circuit design of the system controller based on the digital signal processor is completed, and the working principle and the realization function of each unit of the system are expounded. C language is the main part of the software, combining with the hardware circuit, the main program and each interrupt subroutine of the system are designed, and the software debugging is completed. Finally, the man-machine interface of motor parameters is designed, and the system is debugged synthetically. The system runs reliably. The experimental waveform and experimental data are collected. The results are consistent with the simulation results and the theory, and prove that the system is correct and reasonable.
