Delay-dependent finite-time H∞ filtering for networked control systems: A switched system approach
This paper investigates the problem of finite-time H∞ filtering for networked control systems (NCS) with time delay and packet loss simultaneously.Initially,a switching model is utilized to describe these network-induced imperfections,which can be denoted as three switching subsystems.Furthermore,in the case of packet dropout,the first-order holder (FOH) is constructed to make the controller use the previous state.A full-order filter is designed to estimate the output signal of the NCS.Based on the employed appropriate Lyapunov-Krasovskii functional and auxiliary slack matrices,sufficient conditions are derived in terms of linear matrix inequalities(LMIs),which can ensure the resulting filtering error dynamical system is bounded and satisfies a prescribed H∞ disturbance attenuation in a fixed finite-time interval.Subsequently,a numerical example is exploited to demonstrate the applicability and validity of the proposed filter design method.
