H/sub ∞/ control of discrete-time linear uncertain systems with delayed-state

Abstract

The paper is concerned with H/sub /spl infin// control for discrete time-delay linear systems with parametric uncertainty. We study the problem of robust H/sub /spl infin// state feedback control in which both robust stability and a prescribed H/sub /spl infin// performance are required to be achieved irrespective of the uncertainty and unknown time-delay.
