針對(duì)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(fù)雜的殘氧量對(duì)象進(jìn)行
了研究，分析了殘氧量控制對(duì)象的特性，為了保證燃燒過(guò)程處于合理的空燃比，起到節(jié)能降耗作用，本文重點(diǎn)介紹了在前期已投入運(yùn)行的PLC 控制系統(tǒng)基礎(chǔ)上，增加了FUZZY－PID控制策略，以適應(yīng)復(fù)雜的非線性控制對(duì)象。

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
