Distributed hybrid-triggered H∞ filter design for sensor networked systems with output saturations

This paper is concerned with the distributed hybrid-triggered H∞ filter design problem for sensor networked systems (SNSs) with the output saturations. A distributed hybrid-triggered transmission scheme (DHTTS) is proposed to work in term of time-trigger and event-trigger switching, which can get a balance of saving network resources and improving system performance. Firstly, combining hybrid-triggered scheme and output saturation, the distributed H∞ filtering error system with communication delays is modeled. Then, by using Lyapunov-Krasovskii functional method and linear matrix inequality technique, some sufficient conditions for guaranteeing the asymptotic stability and average H∞ performance of the filtering error system are established, and the distributed filter parameters and hybrid-trigger matrix parameters can be obtained simultaneously. Finally, a simulation example is provided to illustrate the effectiveness of the developed method.
