2、通過該系統(tǒng)在爐頂溫度控制的應(yīng)用來熟悉DCS系統(tǒng)的操作步驟以及DCS系統(tǒng)組態(tài)的使用方法，利用PID控制方案和串級回路控制方案控制爐頂溫度，最終達到最佳控制。通過完成整個工程可以使我們對現(xiàn)今工業(yè)現(xiàn)場的控制系統(tǒng)有一定的了解。其中以硬件組態(tài)（即數(shù)據(jù)庫總控、設(shè)備組態(tài)、圖形組態(tài)、報表組態(tài)、下裝和歷史數(shù)據(jù)查詢），控制器算法為整個系統(tǒng)的重點。關(guān)鍵詞:DCS組態(tài)溫度控制IOPIDtheapplicationofDCSinthetoptemperature
