Cooperative Design of Networked Observers for Stabilizing LTI Plants

With the rapid development of sensor networks in the last decade, the cooperative design for networked observers has received an increasing attention from engineering community. This paper aims at developing a unified framework for cooperative design of networked observers to stabilize LTI plants. Apart from the traditional centralized design of MIMO system, the proposed cooperative design approach only utilizes the local information of each sensor. For undirected networks, this paper obtains a sufficient and necessary condition for the existence of the parameters that lead to the stabilization of the LTI plant. In particular, we give the detailed design procedures for the parameters of networked observers, including feedback gains and the coupling strength. The numerical simulation is also given to validate the proposed theoretical results.
