In order to achieve the intelligent operation of the coal mine power system, the control system of coal mine high-voltage circuit motor mechanism was designed based on the study of coal mine high-voltage circuit breaker and brushless DC motor. Firstly, single neutral PID control algorithm was studied, the simulation model of the control system was established through MATLAB simulation software and PID control parameters were set for simulation analysis. Secondly, the hardware circuit of the system was designed, including motor bridge driver circuit, rotor position detection circuit, IGBT driver protection circuit, system information detect circuit and so on, and software program of the corresponding circuit was designed. Finally, an online experimental platform was designed for control system and high-voltage circuit breakers motor mechanism. The experimental results show that the designed control system can realize the opening and closing operation with rapid response and good stability.
