Hybrid extension and adaptive control

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.
