Research ArticleImproved stabilization method for networked control systems with variable transmission delays and packet dropout

•A static state-feedback controller is designed for the stabilization of networked control systems (NCSs).•Data packet loss and latency arising in NCSs are modeled as a time-varying delay.•Novel Lyapunov-Krasovskii functional and new free-weighting matrices are introduced.•The stabilizing controller gain is obtained by solving a set of linear matrix inequalities (LMIs).•Illustrative examples are given to illustrate the merits of the method.

This paper investigates the problem of stability analysis and stabilization for networked control systems with the network-induced delay and data dropout. In order to obtain less conservative results, a novel augmented Lyapunov-Krasovskii functional is introduced and new free-weighting matrices are employed to make some extra degrees of freedom in the sufficient stabilizability condition. The gain of the memoryless state-feedback controller is computed by solving a set of linear matrix inequalities (LMIs). Illustrative examples are given to verify the applicability and outperformance of the proposed method compared to the existing approaches in the literature.
