針對(duì)工業(yè)鍋爐控制系統(tǒng)的特點(diǎn)，采用將常規(guī)PID 控制與模糊控制相結(jié)合的控制策略，在常規(guī)PID 調(diào)節(jié)器的基礎(chǔ)上，采用模糊推理思想，根據(jù)不同的E、EC 對(duì)PID 參數(shù)Kp、Kl、Kd 進(jìn)行自校正。對(duì)鍋爐汽包液位的控制表明這種模糊PID 控制器可明顯提高系統(tǒng)的性能。
關(guān)鍵詞：模糊PID 控制，參數(shù)自校正、工業(yè)鍋爐、汽包液位

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.
Key words: fuzzy-PID control ，para self-adjusting,，industial boiler，water level in steam drum
