A Round-Robin Type Protocol for Distributed Estimation with $H_\infty$ Consensus

TL;DR

This paper introduces a distributed estimation protocol using a Round-Robin interaction scheme to achieve $H_ abla$ consensus in continuous-time observers over directed networks with sampled interconnections.

Contribution

It provides sufficient conditions for guaranteeing a suboptimal $H_ abla$ consensus level in a distributed robust estimation framework with discrete interaction times.

Findings

Sufficient conditions for $H_ abla$ consensus are derived.

The protocol ensures robust estimation with directed network topology.

Sampled interconnections are effectively incorporated into the estimation process.

Abstract

The paper considers a distributed robust estimation problem over a network with directed topology involving continuous time observers. While measurements are available to the observers continuously, the nodes interact according to a Round-Robin rule, at discrete time instances. The results of the paper are sufficient conditions which guarantee a suboptimal $H_\infty$ level of consensus between observers with sampled interconnections.
