H ∞ fault detection for a class of T - S fuzzy model - based nonlinear networked control systems ⋆

In this paper, a robust H∞ fault detection filter is designed for a class of discretetime nonlinear networked control systems via T-S fuzzy model with multiple bounded state delay and random packet dropout induced by the limited bandwidth of communication networks. Our aim in this paper is to analyze and design a robust H∞ full-order fault detection filter, such that the filtering error dynamics is asymptotically mean-square stable with a prescribed H∞ performance level. Sufficient conditions for the existence of the desired filter are presented. Finally, an example is given to illustrate the effectiveness and applicability of the proposed new design method.
