Robust Fault Detection for Network-based System with Time-Varying Bounded Delay

摘要

A robust fault detection approach for network-based system is discussed in this paper.The fault detection problem is converted into fault detection filter design.The network-induced delay is assumed to have both the upper bound and the lower bound,which is more general compared with only considering the upper bound.The Lyapunov-Krasovskii functional and the linear matrix inequality (LMI)-based procedure are adopted to design the filter.And the filter can guarantee that the estimation error satisfies the H∞ constraint.Fault detection filter is designed for a flight control system and the effectiveness is verified by the simulation results.
