Network-based event-triggered filtering for markovian jump systems

The problem of event-triggered H_∞ filtering for networked Markovian jump system is studied in this paper. A dynamic discrete event-triggered scheme is designed to choose the transmitted data for different Markovian jumping modes. The time-delay modelling method is employed to describe the event-triggered scheme and the network-related behaviour, such as transmission delay, data package dropout and disorder, into a networkedMarkovian time-delay jump system. Furthermore, a sufficient condition is derived to guarantee that the resulting filtering error systemis stochastically stable with a prescribed performance index. A co-design method for the H_∞ filter and the event-triggered scheme is then proposed. The effectiveness and potential of the theoretic results obtained are illustrated by a simulation example.
