Guaranteed cost fault tolerant control of the networked control systems based on LMI method

The problem of guaranteed cost fault-tolerant control for networked control systems (NCSs) is discussed in this paper. Based on Lyapunov stability theory and linear matrix inequality (LMI), the sufficient conditions which can meet a cost function for closed-loop networked control systems possessing robust integrity against actuator failures are given by adopting memory state feedback control law, and the robust fault-tolerant controller is designed via solving several linear matrix inequalities. Finally, the numerical example is given to demonstrate the effectiveness and feasibility of the proposed approach..
