Event-triggered Finite-Time H∞ Filtering for Networked Systems under Deception Attacks

Abstract This paper is concerned with event-triggered H∞ filter design for a networked system suffering stochastic deception attacks in the sense of finite-time boundedness. Firstly, a networked filtering error model is well constructed by taking the effect of deception attacks and event-triggered scheme into account. Then, two sufficient conditions are derived to ensure that the resultant filtering error system is finite-time bounded with a prescribed H∞ performance, where the feasible H∞ filter parameters and the event-triggered communication parameters can be obtained in a unified framework. Finally, the effectiveness of proposed method is demonstrated through a tunnel diode circuit system.
