Aiming at such problems in combustion system of homemade middle and miniature boiler, as a complex system with the character of dead zone, time variation, serious non - linearity, large time delay, coupling and a lot of disturbance, this paper presents a new set of optimal control resources. by using well - matched control method on system, stable automatic running is realized. having the serious divulgence coals difference a lot from each other in character, instability of chemistry, value of lowest emission of heat, home - made boiler controller is not at all ideal. instead of traditional model that controls the ratio based on proportional control or with the correct signal of the amount of oxygen, this paper, combined with intellect control theory - - fuzzy control and self - optimizing concept, propounded a kind of fuzzy self - optimizing controller to be used in air supplying system of the boiler, and expatiates on the idea of dividing the control process into two parts, dynamic and static to realize, thus meets the demand of homemade boiler economic running

    本設計針對國產中、小型電站鍋爐燃燒系統參數時變、嚴重非線性、干擾因素復雜、耦合嚴重、模型不易確定的特點，提出多變量協調控制方案，解決了系統可控性差，難以實現穩定自動運行的問題；在此基礎上，改變以往以煙氣含氧量控制送風的傳統模式，針對國產電站鍋爐設備主體及一、二次送風迴路泄露嚴重，煤種混雜、成分不穩定、燃燒發熱值低、燃燒效率不高等問題，應用智能控制理論中的模糊控制技術，結合自尋最優控制的思想，設計了一種模糊自尋優控制器，應用在電站鍋爐送風控制系統上，並闡述了動靜態兩種實現途徑，通過在線優化風煤配比，實現最佳經濟燃燒，切實保障了鍋爐的經濟運行。
