摘要: This article is devoted to the design of a fuzzy-observer-based H∞ control for an uncertain Takagi–Sugeno fuzzy system with the existence of external disturbance and unavailable state variables. First, an augmented fuzzy model is built by integrating the system state with the output disturbance to create a new variable. Based on Lyapunov theory and linear matrix inequality tools, we derive sufficient conditions for the existence of the fuzzy-observer-based fuzzy controller guaranteeing a generalized H∞ performance level. A decoupled method is proposed in this study to transform the nonlinear matrix inequality (nonlinear matrix inequality) conditions into some LMI forms. Finally, the procedure of the fuzzy-observer-based H∞ control design is summarized and the effectiveness is demonstrated with a practical example. 出版者: London, England: SAGE Publications 出版日期: 2012-11 出處: Proceedings of the Institution of Mechanical Engineers.
