Asynchronous Event-Triggered Finite-Time Filtering for Networked Switched T-S Fuzzy Systems

摘要

This paper investigates the problem of event-triggered finite-time robust filtering for a class of networked switched T-S fuzzy systems. By adopting the extended dissipative performance index, the H-infinity and L-2 - L-infinity filtering problems can be solved in a unified framework. We propose an event-triggered scheme to save the network resources. Under the event-triggered scheme, the filter is not synchronized with the corresponding subsystem. By constructing a reasonable Lyapunov-Krasovskii function, we give sufficient conditions for the finite-time extended dissipative of the filtering error system. We employ the T-S fuzzy models to represent the nonlinear subsystems. The filter gains can be obtained by solving some matrix inequalities. Finally, an example is presented to show the efficiency of the method.
