Fault detection for networked systems with multiple packet dropouts
摘要
Abstract
The problem of robust fault detection is investigated for networked uncertain systems with multiple packet drop-outs.The uncertain plant is represented by polytopic discrete-time model,and stochastic variables with general probability dis tributions are utilized to characterize the multiple packet-dropout phenomenon.The conditions for the existence of the robust fault detection filter are proposed by using Lyapunov stability theory of stochastic systems and a parameter-dependent ap-proach.The robust fault detection filter makes the error between the residual signal and the weighed fault signal as small as possible,and its gains can be obtained via the feasible solutions to a set of linear matrix inequalities.Simulation examples illustrate the effectiveness of the proposed method.关键词
