✦ Synopsis

Al~tmct~A new algorithm for the design of decentralized observation schemes for large-scale interconnected systems is presented. This algorithm offers a constructive procedure based on a stability result that employs the notion of block diagonal dominance in matrices, and is shown to improve considerably upon the existing results for the decentralized observer design problem. A principal contribution of this paper is the demonstration of how the observer gains can be tailored systematically to the existing interconnection pattern within the overall system. Although the present results are developed in the context of decentralized observation, they can be extended to the design of decentralized stabilization algorithms and to the design of decentralized model reference adaptive identification schemes.
