    Abstract: Based on the overall circuit diagram of double closed-loop control system controlled by the STM32F103C6 chip, this paper makes designs of drive circuit, inverter circuit, speed detection circuit and current detection circuit of the brushless DC motor. The brushless DC motor can run smoothly and quickly reach an accurate value when the speed changes through applying PID algorithm and the double closed-loop speed regulation. In addition, the double closed-loop detection algorithm can be optimized to make the speed regulation more accurate.The whole system has been simulated in the Proteus, and the experimental results show that the system structure design is reasonable,the hardware design scheme is feasible, and the control algorithm is correct.
