A constructive procedure for the design of an informationally decentralized stabilization scheme for large-scale interconnected systems is presented. The design procedure is based on a stability result that uses the notion of block-diagonal dominance in matrices and considerably improves on the existing results in either enlarging the class of interconnections for which the design of a stabilization scheme can be satisfactorily conducted or yielding lower values of controller gains for a given interconnection pattern. It is demonstrated how the controller gains can be tailored systematically to the existing interconnection pattern within the overall system.
