ROBUST H2/H∞ DYNAMIC OUTPUT-FEEDBACK CONTROL SYNTHESIS FOR SYSTEMS WITH POLYTOPE-BOUNDED UNCERTAINTY

This paper presents a strategy for robust H2/H∞ dynamic outputfeedback control synthesis, with regional pole placement, applied to linear continuous-time time-invariant systems with polytope-bounded uncertainty. The proposed synthesis approach is based on a multiobjective optimization algorithm applied directly in the space of controller parameters. The H2 and H∞ norms, computed in all polytope vertices and in possible “worst case” interior points are taken as the optimization objectives. A branch-and-bound algorithm based on LMI guaranteed cost formulation is applied to validate the controller design. Examples are presented to show the effectiveness of the proposed strategy, including examples of full order and low order, centralized and decentralized control systems. Copyright c ©2005 IFAC.
