摘要：
In this paper, the non-fragile finite-time filtering problem is studied for a class of nonlinear Markovian jumping systems (NMJSs) with time delays and uncertainties. To design the mode-dependent non-fragile state filter, Takagi-Sugeno (T-S) fuzzy models are employed to represent the time-delayed and uncertain NMJSs. Then, based on the Lyapunov-Krasovskii functional, a sufficient condition is derived for the existence of a desired non-fragile filter which also guarantees the finite-time boundness of the filtering error dynamical NMJSs. By this criterion, the approach to designing a non-fragile fuzzy filter is developed in terms of linear matrix inequalities. Finally, a numerical simulation is provided to illustrate the performance of the proposed method.
