Decenralized Robust Servomechanism Problem for Descriptor-type Discrete-time-delay Systems
Author:
Abstract: Decentralized stabilizing controller design for a system to achieve robust tracking of certain
reference signals despite certain disturbances and modeling uncertainties is an important problem, which is
known as the decentralized robust servomechanism problem. In this work, this problem is considered for
linear time-invariant descriptor-type discrete-time-delay systems. The necessary and sufficient conditions for
the solvability of this problem are presented. The structure of the controller which solves this problem, when
a solution exists, is also given.
