Dongnian Jiang · Kongzhi yu juece · 2010
For a class of nonlinear networked control system(NCS) with parameter uncertainties,considering both network-induced delay and packet dropout in transmission,based on a T-S fuzzy model,and by using Lyapunov-Krasovskii functional, the delay-dependent sufficient condition of robust H_∞integrity for NCS with failures of actuator and sensor is analyzed. And the robust H_∞fault-tolerant controller gain can be obtained by solving several linear or nonlinear matrix inequalities. Finally,a simulation example illustrates the effectiveness and the feasibility of the proposed approach.
