Abstract:

This paper proposes a distributed filtering scheme over sensor networks with topology switching and topology-dependent event-triggered transmission schemes. A new monitoring mechanism is introduced to identify the topology switching instants, and the system output is sampled by sensors when the network topology switches. Based on the time-varying sampled-outputs, a group of distributed topology-dependent event-triggered transmission schemes is introduced to reduce the amount of transmitting sampled-data. Under a unified framework of multiple switching topology modes, the event-triggered transmission schemes, and the network-induced delays, the networked filter error system is modeled as a switched time-delay system. By using a Lyapunov-Krasovskii functional, a bounded real lemma is obtained such that the filtering error system is asymptotically stable with a prescribed attenuation level, and a co-design method on the event-triggered parameters and the networked filter gains is also proposed. Finally, an illustrative example is presented to verify the effectiveness of the proposed results.
