Abstract
This paper is concerned with event-driven filtering for networked switched systems with unreliable links. In order to improve the anti-interference performance of the filter, stochastic cyber-attacks and random parametric perturbations are considered in the filter design. The update of the measurement is determined by a newly proposed intermittent event-driven mechanism, which helps to save limited bandwidth resources. By constructing a new Lyapunov-Krasovskii functional (LKF) without positivity and continuity constraints in a triggering interval, sufficient conditions are obtained such that the filtering error system is exponentially mean-square stable with a weighted H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> performance. The resilient filter and event-driven mechanism are then co-designed. Finally, the results obtained are applied to a switched circuit system.
Highlights
I N the past two decades, the internet has developed rapidly, and the communication technologies have been continuously innovated
By considering deception attacks and denial-of-service attacks at the same time, Liu et al [10] dealt with the event-triggered control problem for T-S fuzzy systems
How to develop a new Event-driven mechanism (EDM), such that the less restrictive Lyapunov-Krasovskii functional (LKF) method can be successfully introduced into the investigation of even-driven filtering problem for networked switched system, and obtain less conservative result, is the other motivation of this paper
Summary
I N the past two decades, the internet has developed rapidly, and the communication technologies have been continuously innovated. Discontinuous LKF method [37] and looped LKF method [38] could lead to less conservative results for sampled-data control systems These methods can not be applied directly in the literature [33]–[36] since it is difficult to coordinate the switching instants and triggering instants in the analysis based on the proposed EDMs. how to develop a new EDM, such that the less restrictive LKF method can be successfully introduced into the investigation of even-driven filtering problem for networked switched system, and obtain less conservative result, is the other motivation of this paper. Inspired by the above discussion, in this paper: 1) To reduce the update of the measurements, an event-driven filter is designed with consideration of stochastic cyber-attacks and random parametric perturbations.
