Event-triggered H∞ Filter Design for Nonlinear Time-delay Systems with Packet Dropouts

This paper is concerned with the event-based H∞ filtering problem for networked discrete-time nonlinear systems with time-varying delay and packet dropout. In this system, event-triggered communication mechanism is adopted, and both time-varying delay and packet dropout are taken into consideration. The objective of the paper is to design a filter such that the augmented system is exponentially mean-square stable. By utilizing stochastic analysis techniques, sufficient conditions are established for the existence of proposed filter satisfying the filtering performance constraints. The desired filter parameters could be obtained by solving the certain linear matrix inequality (LMI). A simulation example is used to demonstrate the effectiveness of the proposed event-based filtering method.
