摘　　要：锦西石化分公司南蒸馏DCS使用的是FOXBORO公司的I/A控制系统,它的基本环节的控制算法是古典的PID算法。这种算法对于线性非时变系统,控制效果良好,但对于某些复杂环节,诸如非线性、大时滞、时变、强耦合系统,控制起来很难。为此,使用无模型控制系统来控制加热炉的温度,收到了满意的效果。DCS of south fractionation equipment of Jinxi Petro-chemical Factory is I/A control system of Foxboro Company. In this control system, control algorithm of basically control loop is classical PID. Control effect of PID regulator is satisfactory for linear time-invariant system. But, in some complex control loops, such as nonlinear, large scale time delays, time varying and strong coupling systems, control effect is no satisfactory. In order to solve this kind of difficult problem, the model free control system is applied, and good results are obtained.
