✦ Synopsis

The decentralized robust control of a servomechanism problem for a composite system with interconnected subsystems is considered in this paper. Previous work is extended in two important ways. Firstly, each subsystem is assumed to have its own set of local reference and disturbance signals. Secondly, the perturbations which arise due to modelfing uncertainty are shown to have a structured form due to interconnection topology. Necessary and sufficient conditions, together with a characterization of all decentralized robust controllers which enable asymptotic tracking to occur, independent of disturbances and structured perturbations in the plant, are obtained.
