模糊PID 控制在工业锅炉控制系统中的应用

针对工业锅炉控制系统的特点，采用将常规PID 控制与模糊控制相结合的控制策略，在常规PID 调节器的基础上，采用模糊推理思想，根据不同的E、EC 对PID 参数Kp、Kl、Kd 进行自校正。对锅炉汽包液位的控制表明这种模糊PID 控制器可明显提高系统的性能。

Application of the fuzzy-PID control in industrial boiler control system Pan Xiangliang Luo Liwen （School of Electrical and Information Engineering Shanghai Jiao Tong University 200420） Abstract:A control method based on combination ot fuzzy control and PID control is presented for characteristics of industrial boilers control system. The new kind of controller based on traditional PID controller employs fuzzy reasoning to accomplish PID parameters self-adjusting. Actual application for control of water level in steam drum presents that the fuzzy PID controller can improve the performance of system obvisouly.
