炭素回转窑三级控制系统的设计

Design of Three Level Control System in Carbon Rotary Kilns

炭素回转窑具有时变性、大惯性和大滞后性等特点,目前常规的控制策略难以控制,提出炭素回转窑的三级控制系统方案。第一级检测系统扫描分析回转窑煅烧带的温度、位置和长度;第二级基础级自动控制系统基于模型预测控制方法,实现回转窑进料速度、窑尾温度和负压的多变量协调控制;第三级智能决策系统以Fuzzy Clips推理机为引擎,推理输出工况的故障分析和决策信息,实现可靠高效的回转窑燃烧控制,并最大限度地延长其使用寿命。

Due to the presence of carbon rotary kiIns have the characters of time-varying parameters,Iarge inertia and Iarge Iag,the conventionaI controI strategy is difficuIt to be used in carbon rotary kiIns; controI effectiveIy at present.To soIve this probIem,three IeveI controI system scheme of carbon rotary kiIn is proposed in this paper.
