Abstract :
In this paper, a switching control algorithm for the stabilization of network control systems (NCS) with time-varying delay in the presence of disturbance is investigated. Discrete-time equivalent model of NCS with time delay and disturbance is derived. It is assumed that the time delay is unknown and time-varying, nonetheless bounded with a known bound. It is also assumed that the system is highly uncertain, and a set of controllers are given, which stabilize the whole uncertain parameter space. A switching scheme is developed subsequently to find the stabilizing controller at any time. A thorough stability analysis for NCS under the mentioned control scheme is provided. Simulation results are presented to show the efficacy of the proposed method in stabilization of an unstable NCS subject to time-varying delay and disturbance.
