다국어 초록 (Multilingual Abstract)

This paper deals with fuzzy H_∞ filtering problem of discrete-time nonlinear Markovian jump systems with state and output time delays. The purpose is to design fuzzy H_∞ filter such that the corresponding estimation error system with time delays and initial state uncertainties is stochastically stable and satisfies an H_∞ performance level. A sufficient condition for the existence of fuzzy H_∞ filter is given in terms of matrix inequalities. In order to relax conservatism, a stochastic mode dependent fuzzy Lyapunov function is employed. The Lyapunov function not only is dependent on the operation modes of system, but also includes the fuzzy membership functions. An illustrative example is finally given to show the applicability and effectiveness of the proposed method.
