Dynamical Orders of Decentralized H-infinity Controllers

    Research output: Book/ReportReportResearchpeer-review


    The problem of decentralized control is addressed, i.e. theproblem of designing a controller where each control input is allowedto use only some of the measurements. It is shown that such problemsthere does not always exist a sequence of controllers of bounded orderwhich obtains near optimal control. Neither does there exist an infinitedimensional optimal controller. Using the insight of the line of proofof these results, a heuristic design algorithm is proposed for designingnear optimal controllers of increasing orders.
