英文摘要	In this paper, the problem of robust integrity considering actuator structural failures for a class of uncertain nonlinear networked control system (NNCS) subject to actuator saturation is investigated. By utilizing the delay-dependent Lyapunov method and convex combination expression of input saturation function, the less conservative stability criteria and the approach of robust fault-tolerant state feedback controller are derived for the control problem. By introducing a definition of the fault-tolerant attraction domain and solving an optimization problem with LMIs constraints, the maximum fault-tolerant attraction domain can be estimated. The key features of the proposed approach include the use of a tighter bounding technique for reducing conservativeness and the introduction of augmented matrix items into the Lyapunov-Krasovakii functional for reducing computational demand. Finally, an example is used to illustrate the effectiveness and the feasibility of proposed approach. © 2013 IEEE.
