Objective-centered formulation of an adaptive fuzzy control scheme. (English) Zbl 1232.93056
Summary: This paper presents a new adaptive fuzzy control scheme that is formulated and constructed directly in the control objective space. The idea of the objective-centered formalism on the basis of decomposition of closed-loop response profile is clarified first, followed by a detailed description of the scheme. Unlike the existing adaptive fuzzy control methods, the rules and the membership functions of the fuzzy controller in the new scheme are fixed and the adaptation is done on the input and output weighting factors of the fuzzy controller. A simulation analysis is conducted to evaluate the controller performance in regulating a structure-varying process, and to illustrate the advantage of the scheme in controlling plants that cannot be easily handled by other control approaches.
