摘　　要：通过对氯化氢合成机理的分析,找出影响氯化氢合成过程氢氯比的主要因素.针对氯化氢合成过程这样一个非线性耦合、大滞后、多变量、多干扰的控制对象,引入链系统控制方法对合成过程的氢氯比进行控制.分析合成过程中各因素之间的因果关系,建立由4个单元模型和两条因果链构成模型.通过现场采集的数据进行仿真,结果显示采取的链系统控制方法的氯化氢合成过程,系统实时性、稳定性和抗干扰能力明显增强,控制效果良好.The mechanism of hydrogen chloride synthesis is analyzed, and the main factors affecting the ratio of chlorine and hydrogen in hydrogen chloride synthesis are found out. For hydrogen chloride synthesis procedure which is nonlinearly coupling, lagged, multi-variant and multi-interaction control object, a chain system control method is brought forward to control the ratio of chlorine and hydrogen in hydrogen chloride synthesis process. The cause-effect relationships of key factors are analyzed, then build the model which consisted of four unit models and two causality chains. Through the field data simulation, the results show that the chain system model has strong real-time performance, stability, anti-interference ability, and the control effect is good.
