Guaranteed cost fault-tolerant control of networked control systems with sensor failure
Résumé
Based on the network transmission with network-induced delay and packet dropout,guaranteed cost fault-tolerant control for closed-loop networked control systems(NCSs) with sensor failure is studied,aiming at the NCSs with the uncertainty of the parameters matrix,based on Lyapunov stability theory and linear matrix inequalities(LMIs),the sufficient conditions of guaranteed cost control with certain upper bound and fault-tolerant control for the NCS with sensor failure are deduced.The corresponding design method of guaranteed cost fault-tolerant controller is presented by using LMIs.The proposed control algorithm,which improves the reliability of the system,is propitious to optimize the integrative capability of the system.Numerical simulation demonstrates the effectiveness and feasibility of the proposed method.
