Design of Interval Observer for Linear Discrete Parameter-Varying Systems under Stealthy Attacks
摘要
Abstract
To address the state estimation problem of network control systems under stealthy attacks,this study investigates the design of a robust interval observer based on the L∞ filtering theory for linear discrete parameter-var-ying systems in a stealthy attack environment.The boundary information of the attack signal is obtained according to the inherent characteristic of the concealed attack.Utilizing the boundary information of the attack signal and the system state,a robust interval observer is designed for the parameter-varying system employing L∞ filtering tech-niques to mitigate the effects of unknown perturbations,stealthy attack signals,and parameter uncertainties.Accu-rate system state estimation under stealthy attacks is achieved by solving a set of linear matrix inequalities to derive the gain matrix of the system.The results of numerical simulation examples prove the accuracy of the proposed meth-od.关键词
