Abstract

In this paper, we concern with robust stability of networked control systems (NCSs) by taking the effects of both the time-varying network-induced delay and data packet dropout into consideration. A new delay decomposition approach to time-varying delay is proposed and an appropriate Lyapunov-Krasovskii functional is constructed to derive some less conservative stability criteria. No slack matrix variable is introduced and overly bounding for some term is avoided. Furthermore, two numerical examples are given to show the effectiveness of the proposed results.
