高炉火道温度控制具有非线性、多扰动特点，且时滞较大，实时性和温度控制品质较差。提出一种基于黄金分割优选解析设计模式的高炉温度专家控制方法，以提高煤气过程能源利用率。利用黄金分割优选解析方法设计了专家系统补偿函数与温度控制规则，采用加权组合预测的方式，取得控制量区域量化值，进行控制品质优选解析设计，完成高炉火道温度控制模糊专家系统设计。仿真测试表明，实测的高炉火道温度与目标火道温度变化趋势基本一致，与设定的基准值波动幅度不大，展示了温度控制预测较好的跟踪性能。温度控制预测误差远远小于传统方法。

The blast furnace flue temperature control was nonlinear, multi disturbance, and large time delay, and the temper-ature control quality was bad. A blast furnace temperature control method of coal gasification process based on golden sec-tion quality optimizing analysis was proposed. Using the golden section analytic design method of the compensation func-tion to design the rule of temperature control, the blast furnace flue temperature fuzzy expert control system design was com-pleted. Simulation test shows that real measured blast furnace flue temperature and target flue temperature change in same tendency, which has small fluctuations with the set reference value. It shows the good tracking performance of temperature control and prediction, the prediction error is much small than the traditional method. It has good reference value in the coke oven and blast furnace temperature control field.
