ROBUST GUARANTEED COST CONTROL OF UNCERTAIN LINEAR TIME-DELAY SYSTEMSUSING DYNAMIC OUTPUT-FEEDBACK

This paper is concerned with robust guaranteed cost control of uncerta in Linear time-delay systems using dynamic output feedback. The uncert ain systems tackled in this paper involve uncertainty in quadratic con strained form which includes the well-known norm-bounded time-varying uncertainty as a special case. We show that the feasibility of several matrix inequalities guarantees the solvability of the addressed probl em. Furthermore, we propose an iterative algorithm to numerically chec k the feasibility of the concerned matrix inequalities using linear ma trix inequalities (LMIs). (C) 1998 IMACS/Elsevier Science B.V.
