    Conference Proceeding: An LMI-based stable fuzzy control of nonlinear systems and its application to control of chaos
    H.O. Wang, K. Tanaka
    [show abstract] [hide abstract]
    ABSTRACT: We present a systematic framework for the stability and design of nonlinear fuzzy control systems. First we represent a nonlinear plant with a Takagi-Sugeno fuzzy model. Then a model-based fuzzy controller design utilizing the concept of so-called “parallel distributed compensation” is employed. The main idea of the controller design is to derive each control rule so as to compensate each rule of a fuzzy system. The design procedure is conceptually simple and natural. Moreover, the stability analysis and control design problems can be reduced to linear matrix inequality (LMI) problems. Therefore they can be solved efficiently in practice by convex programming techniques for LMIs. The design methodology is illustrated by application to the problem of modeling and control of a chaotic system-Chua's circuit

    ABSTRACT: In this paper we explore the interaction between fuzzy control systems and chaos. First we show that fuzzy modeling techniques can be used to model chaotic dynamical systems. Then we apply some of the newly developed fuzzy control design techniques to the control of chaotic systems. The design procedure is conceptually simple, natural and computationally efficient. Therefore the proposed fuzzy methodology represents a systematic and effective framework for modeling and control of chaotic systems. The method is illustrated by application to Chua's circuits

    ABSTRACT: Presents a design methodology for stabilization of a class of nonlinear systems. First, the authors represent a nonlinear plant with a Takagi-Sugeno fuzzy model. Then a model-based fuzzy controller design utilizing the concept of the so-called “parallel distributed compensation” is employed. The main idea of the controller design is to derive each control rule so as to compensate each rule of a fuzzy system. The design procedure is conceptually simple and natural. Moreover, the stability analysis and control design problems can be reduced to linear matrix inequality (LMI) problems. Therefore, they can be solved efficiently in practice by convex programming techniques for LMIs. The design methodology is illustrated by application to the problem of balancing and swing-up of an inverted pendulum on a cart
