  • Abstract
    A new constructive procedure for the design of a decentralized observation scheme for large-scale interconnected systems is presented. The design procedure is based on a stability result that employs the notion of block diagonal dominance in matrices. The obtained algorithm is shown to considerably improve upon the existing results for the decentralized observer design problem. A major contribution of this paper is the demonstration of how the observer gains can be tailored 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 decentralised stabilization algorithms and to the design of decentralized model reference adaptive identification schemes.
