摘要:In this paper, the problem of stability for networked control systems (NCSs) is investigated. Considering both the time-varying network-induced delay and data packet dropouts, NCSs are transformed into typical linear systems with interval time-varying delay. Based on the obtained model, a new delay-dependent stability criteria in terms of linear matrix inequalities (LMIs) is provided by constructing a novel time-dependent Lyapunov-Krasovskii functional. The tighter integral inequalities are used to deal with the cross-product terms arose from the time derivative of the Lyapunov-Krasovskii functional for obtaining much less conservative result. Compared with some previous ones, the proposed method introduces fewer matrix variables and has less conservatism. A numerical example is provided to demonstrate the effectiveness and the benefits of the proposed method.
