ASYMPTOTIC STABILITY AND FINITE-TIME STABILITY OF NETWORKED CONTROL SYSTEMS: ANALYSIS AND SYNTHESIS

This paper focuses on the problems of asymptotic stability and finite-time stability (FTS) analysis, along with the state feedback controller design for networked control systems (NCSs) with consideration of both network-induced delay and packet dropout. The closed-loop NCS is modeled as a discrete-time linear system with a time-varying, bounded state delay. Sufficient conditions for the asymptotic stability and the FTS of the closed-loop NCS are provided, respectively. Based on the stability analysis results, a mixed controller design method, which guarantees the asymptotic stability of the closed-loop NCS in the usual case and the FTS of the closed-loop NCS in the unusual case (that is, in some particular time intervals, large state delay occurs), is presented. A numerical example is provided to illustrate the effectiveness of the proposed mixed controller design method.
