Abstract: The brushless DC motor has big speed tracking error during the load operation condition, and the torque ripple is obvious. In order to solve the problem, a sliding mode control algorithm based on the integraltype sliding surface was proposed in this paper. The simulation model of the speed control system was built in the Simulink and the related simulation experiments were done. For the motor control system, the speed is regulated with the sliding mode controller, and the current is regulated with the PI controller. Simulation results show that the system with sliding mode control algorithm has fastest dynamic response and smallest speed tracking speed error, compared with the PI control algorithm and fuzzy PI control algorithm. In addition, the torque ripple of the designed system is not obvious, and the motor parameter variation has little influence on the control system, so it has strong robustness.
