In general, due to the interaction among subsystems, it is difficult to design an H ∞ filter for nonlinear interconnected systems. This paper introduces a decentralized H ∞ fuzzy filter design for nonlinear interconnected systems with multiple time delays via T-S fuzzy models. The T-S fuzzy model consists of N time-delay T-S fuzzy subsystems. The decentralized H ∞ filter is designed based on this model, which the asymptotic stability and a prescribed H ∞ performance index are guaranteed for the

A simulation example is given to show the effectiveness of this approach.
