摘　　要：针对自适应控制只能处理渐变问题和量变问题的局限性,探讨运用可拓控制对自适应控制进行补充的问题,建立一种新型的控制方法———可拓自适应混杂控制方法.该控制方法的体系结构由自适应控制器和可拓控制器两个部分组成,中间通过基于可拓集合的智能开关来转换连接.自适应控制器的输出计算是基于可拓集合的测度模式的,它只依赖于控制特征量的先验经典域和节域,无需预先提供数学模型或控制结构信息.可拓控制器由可拓模型、关联度计算、可拓分析、可拓变换和优度评价5个模块组成,它善于处理非渐变和质变的控制问题.Considering the fact that the adaptive control can deal only with the cases of gradual and quantitative changes,the paper discusses the possibility that the extension control can form a supplement to adaptive control,and proposes a novel control method called hybrid extension and adaptive control.The system structure of the control method is composed of adaptive controller and extension controller,which are connected by an intelligent control switch based on extension set.The output calculation of the adaptive controller is based on the measure partition of extension set.It is built only upon the known classic field and limitation field and does not need provided mathematical models and provided control structure information.The extension controller,good at dealing with big change and qualitative change,is composed of such five modules as extension model,dependent degree calculation,extension analysis,extension transformation and excellent degree evaluation modules.
