摘　　要：焦炉配煤炼焦过程是存在诸多不确定性、无法用数学模型描述的复杂工业过程 ,传统控制方法难以实施控制 .根据焦化理论和生产所获工业数据构造数学模型 ,以群体专家经验得到的定性知识构成规则模型 ,将解析的数学模型与基于知识的规则模型相结合 ,采用定性定量综合集成方法 ,建立焦炭质量预测模型 ,提出了配煤比计算的实用算法 ,并实时控制配煤流量 .系统于 1994年正式投入工厂运行 ,焦炭质量预测精度达到 95% ,配煤准确率达到97% .The coal blending and coking process,in which much uncertainty exists,is too complicated to describe with mathematical models,and it can not be controlled properly by traditional methods.According to the coking theory and using statistical data acquired from industry processes,a mathematical model is designed and a rule model is proposed with qualitative knowledge derived from experts' experience.The rule model is combined with the mathematical model,and qualitative and quantitative methods are integrated to build up a model for prediction of coke quality and to compute the blending ratio of coal.Furthermore the flow of each kind of coal is controlled.Since 1994 the system has been running in a plant with accuracy of coal blending and prediction precision of coke quality up to 97% and 95%,respectively.
