摘要：针对传统PID理论不能适应无刷直流电机动态运行特性的缺点，提出将积分分离模糊控制与经典PI相结合，构成了无刷直流电机速度电流双闭环控制系统。设计了以LPC1769微处理器为核心的无刷直流电机硬件测试系统中，并在该系统中实现了积分分离模糊控制的软件设计。仿真和实际测试表明，积分分离模糊PI控制系统具有响应速度快，超调小，抗负载扰动能力强，更适合于无刷直流电机的动态控制。

Abstract: Aiming at the shortcomings that traditional PID can not adapt to the dynamic characteristics of the brushless DC motor，integral separation fuzzy control combined with classical PI was proposed to constitute brushless DC motor speed current double closedloop control system. With the core of LPC1769 microprocessor, the hardware system was designed, in which the integral separation fuzzy control software was achieved. Simulation and practical test show that integral separation fuzzy control strategy has fast response, small overshoot, and strong ability of antidisturbance, which is more suitable for dynamic control of brushless DC motor.
