针对直流调速系统采用传统PID控制方案存在精度低、抗干扰能力差等缺点，将PID控制、模糊控制和微粒群算法相结合，设计双闭环直流调速系统优化控制方案，改善直流系统的调速性能。电流内环采用电流滞环控制，转速外环分别采用传统PID控制器、自适应模糊PID控制器和微粒群优化的自适应模糊PID模糊控制器。在空载和扰动情况下，分析转速外环对双闭环无刷直流调速系统控制效果的影响。在MATLAB/Simulink中构建了双闭环无刷直流电机调速系统仿真模型，并对其进行仿真分析。仿真结果表明，无刷直流电机调速系统采用粒子群优化的自适应模糊PID控制器具有最优的动、静态性能和抗干扰能力。

Considering the traditional PID control of DC motor speed regulating system has low precision, poor anti-interference ability, adouble loop DC speed control system was proposed for the design scheme, and BLDCM as the controlled object. In order to improve the dynamic performance of BLDCM speed control system, PID control is combined with fuzzy control and particle swarm optimization algorithm. Besides, the inner current loop adopts current hysteresis control. The speed outer ring adopts traditional PID controller, adaptive fuzzy PID controller and the particle swarm optimization of adaptive fuzzy PID controller. Finally, in the no-load and disturbance conditions, the paper analyzed the control effect of speed outer ring on BLDCM. And in MATLAB/Simulink, a simulation model was builded and analyzed. The simulation results show that, in the three kinds of control methods, the control system adopting the adaptive fuzzy PID controller based on particle swarm optimization has the best dynamic, static performance and anti-interference ability.
