Design and implementation of speed control system based on fuzzy pid algorithm

本文提出了一种基于模糊PID算法的直流电机转速控制系统。利用模糊控制理论对电机转速偏差和转速偏差率进行模糊控制的一系列处理,实现对PID参数的在线整定,输出PWM波驱动控制电机转速。实验结果表明该系统具有响应速度快、超调量小、抗干扰能力强、稳定性能好等优点。

This paper proposes a speed control system of DC motor based on fuzzy PID algorithm.the speed error and its change were used as fuzzy input according to the fuzzy control method,and self-tuning is made.The MCU output the PWM wave to control the DC motor.The result from the lab shows that the system can show a fast response and low overshoot and strong anti-interference ability and strong steady state performerce.
