Abstract

In this paper we deal with the security stability when a communication canal is inserted in the control loops which bring some communication constraints such as induced time delays and packets dropout. Those constraints can degrade the performances of the system or take it to instability that is to say that the control system is not secured. With the aim to keep good performances of the controlled system face of possible changes introduced by the network, it is interesting to introduce new approaches or ameliorate and improving some existing results. In this article we are concerned with the security function of the system with stability analysis and stabilization of networked control systems with network induced time-delay. To achieve this goal a novel augmented Lyapunov-Krasovskii functionals (LKF) is considered to derive the proposed delay dependent LMIs based secured stability conditions. Numerical examples and simulation results are presented to illustrate the effectiveness of the method.
