Robust finite-time boundedness ofH_∞filtering for switched systems with time-varying delay

Abstract

For switched system, switching behavior always affects the finite-time stability property, which was neglected by most previous research. This paper investigates the problem of robust finite-time boundedness of H∞ filtering for switched systems with time-varying delay. Sufficient conditions that can ensure finite-time bounded and H∞ filtering finite-time stability are derived. Based on the average dwell-time approach, the closed-loop system trajectory stays within a prescribed bound. At last, numerical examples are given to illustrate the efficiency of the proposed method.
