Distributed Event-Triggered H_∞ Filtering for Semi-Markov Jump Systems with Quantization and Cyber-Attacks

The problem of distributed event-triggered H_∞ filtering for semi-Markov jump systems is investigated in this paper. The system measurements are collected through a sensor network subject to quantization and random cyber-attacks. Taking the influence of event-triggered scheme, quantization, and cyber-attacks into account, a distributed event-triggered filtering error system is established. A distributed H_∞ filter design scheme is outlined by explicitly characterizing the filter gains through some matrix inequalities. Finally, a numerical example is given to illustrate the effectiveness of the designed distributed event-triggered H_∞ filters.
