摘　　要：设计一种基于模糊PID算法的双闭环直流调速系统,其主要由三相对称交流电压源、晶闸管整流桥、同步6脉冲触发器、转速调节器、电流调节器和直流电机等组成。系统以模糊PID算法为控制核心,由同步6脉冲触发器产生脉冲来实现对直流电机的速度调节。目标转速值确定后,通过仿真对比传统工程整定法和模糊PID算法,结果表明,两种方法都实现了对电机转速的控制,但模糊PID算法的转速曲线更平滑、调节时间更短、超调更小,能满足工控领域要求。A double closed⁃loop DC speed governing system based on fuzzy PID algorithm is designed.The system is composed of three⁃phase symmetrical AC voltage sources,thyristor rectifier bridge,synchronous 6⁃pulse trigger,speed governor,current regulator and DC motor.In the system,the fuzzy PID algorithm is taken as the control core,and synchronous 6⁃pulse trigger is used to produce pulses to realize the speed governing of DC motor.After the target rpm value is determined,the simulation comparison between the traditional engineering tuning method and the fuzzy PID method is carried out.The results show that both methods can control the motor speed,but the fuzzy PID algorithm rotational speed curve is smoother,its adjustment time is shorter and its overshoot is smaller,which can meet the requirements of industrial control field.
