In this work. the structural properties of a class of two level hierarchical systems where N subsystems at the lower hierarchical level are connected through a coordinator in the upper hierarchical level, are studied. The results from this type of analysis can be used in order to determine controllability of the overall system by the coordinator or more generally by any one of the subsystems. A special case where the interconnection pattern is such that the optimum quadratic local control equals the optimum quadratic global control is presented.
Large Scale Systems, decentralized control, structural control, overlapping subsystems.
