Abstract

This paper deals with the problem of delay-dependent robust stability for uncertain stochastic systems with time-varying delay. Improved delay-dependent robust stability criteria are proposed without ignoring any terms by considering the relationship among the time-varying delay, its upper bound and their difference, and using both Itpsilas differential formula and the Lyapunov stability theory. Numerical examples demonstrate the effectiveness and the benefits of the proposed method.
