In this paper, we consider the problem of delay-dependent H1 control of a class of
linear uncertain systems with interval time-varying delay and norm-bounded uncertainties
using Lyapunov-Krasovskii approach. By exploiting a candidate Lyapunov-Krasovakii (LK)
functional and using slack matrix variables in the delay-dependent stability analysis, a less
conservative stability criterion is first derived in terms of linear matrix inequalities (LMIs).
Subsequently, based on the criterion obtained, a delay-dependent condition for the existence
of a static state feedback controller, which ensures asymptotic stability as well as a prescribed
H1 performance of the closed loop system for all admissible uncertainties, is deduced. A
numerical example is employed to demonstrate the effectiveness of the proposed controller.
