Overlapping Decentralized Controller Design for Descriptor-type
Systems with Distributed Time-delay
Author:
Abstract: Decentralized controller design using overlapping decompositions is considered for descriptor-type systems with
distributed time-delay. The approach is based on the principle of extension. In this approach, a given large-scale system is
decomposed overlappingly into a number of subsystems and expanded such that the overlapping parts appear as disjoint. A
decentralized controller is then designed for the expanded system. This controller is then contracted for implementation on
the original system. It is shown that if the decentralized controllers are designed to stabilize the expanded system and to
achieve certain performance, then the contracted controller, which would have an overlapping decentralized structure, will
stabilize the original system and will achieve corresponding performance
