針對鋼鐵企業(yè)中典型的燃油三段連續(xù)式加熱爐控制參數(shù)中最為復雜的殘氧量對象進行
了研究，分析了殘氧量控制對象的特性，為了保證燃燒過程處于合理的空燃比，起到節(jié)能降耗作用，本文重點介紹了在前期已投入運行的PLC 控制系統(tǒng)基礎上，增加了FUZZY－PID控制策略，以適應復雜的非線性控制對象。
關鍵詞：殘氧量；模糊PID 控制；供風量；空燃比
Abstract: It studies the most complicated remaining oxygen parameter for three sector continuous heat-up stove with heavy oil and analyses the nature of remaining oxygen parameter. To ensure the wind- heavy oil in a rational proportion and attain saving energy and reducing consume, It mainly introduces the adding control method of fuzzy PID of remaining oxygen in the base of the formerly PLC control system, in order to adapt the control object with complex and nonlinear.
Key words: remaining oxygen; fuzzy PID; the wind quantity; quantity of wind- heavy oil in a
rational proportion
