摘　　要：针对梅钢混合煤气工艺存在的问题,将混煤工艺分解成热值(配比)、压力、流量三个既相互关联又相对独立的控制子模块,分别确定目标变量、被控对象、执行机构、整定PID参数,同时运用智能控制理念,实现了混合煤气系统的自动运行。In view of the problems existing in the mixed gas process of Meishan Steel,the coal blending process was divided into three control sub modules of calorific val⁃ue(proportioning),pressure and flowrate,which are not only interrelated but also relatively independent.The target variable,controlled object,actuator and PID parameters were deter⁃mined respectively.At the same time,the intelligent control concept was used to achieve au⁃tomatic operation of the mixed gas system.
