Aiming at precision and stability of brushless DC（BLDC） motor

a control system based on STM32 microprocessor is designed. The system adopts current feedback and rotor position feedback to realize double closed-loop control

at the same time

fuzzy adaptive PID control algorithm which increases the control precision of the system reduce of motor. In design of circuit

IR2136 drive chip is used and circuit is added

which assure statility and anti-interference of system operation. By experimental analysis and verification

the system operates stably

control precision of BLDC is high

response velocity is fast

and overshoot is small.
