摘要

This paper deals with the problems of robust delay-dependent stability and H-infinity analysis for Markovian jump linear systems with norm-bounded parameter uncertainties and time-varying delays. In terms of linear matrix inequalities, an improved delay-range-dependent stability condition for Markovian jump systems is proposed by constructing a novel Lyapunov-Krasovskii functional with the idea of partitioning the time delay, and a sufficient condition is derived from the H-infinity performance. Numerical examples are provided to demonstrate efficiency and reduced conservatism of the results in this paper.
