Conditions for detectability in distributed consensus-based observer networks
arXiv:1303.6397 · doi:10.1109/TAC.2013.2256675
Abstract
The paper discusses fundamental detectability properties associated with the problem of distributed state estimation using networked observers. The main result of the paper establishes connections between detectability of the plant through measurements, observability of the node filters through interconnections, and algebraic properties of the underlying communication graph, to ensure the interconnected filtering error dynamics are stabilizable via output injection.
