一、概述在化工过程控制中,控制对象的特性有时随周围环境缓慢或急剧的变化,例如化学反应炉,其控制对象特性随时间和原料的不均匀性等因素而改变,对于这些实际控制问题,单纯用线性二次型最优控制问题已不能适应过程控制的要求。因此,必须考虑系统在运行中“跟上”环境的变化,使控制规律适应对象的变化并能实现和维持高的控制性 I. Overview In the chemical process control, the characteristics of the control object sometimes with the surrounding environment slowly or dramatically changes, such as chemical reactors, the characteristics of the control object with the time and raw material heterogeneity and other factors change, for these practical control problems , Simply using linear quadratic optimal control problems can not adapt to the requirements of process control. Therefore, we must consider the system in the operation of “keep up” changes in the environment, the control law to adapt to changes in the object and to achieve and maintain high controllability
