Aiming at the nonlinear network system, the problem of the system stability for a class of networked control system (NCS) with time-delay, uncertainty and external disturbance is investigated based on T-S fuzzy model. The fuzzy state feedback controller is designed by using parallel distributed compensation (PDC) technique. Furthermore, Lyapunov method is employed to obtain the sufficient conditions for the stability of system combined with the Razumikhin theorem and linear matrix inequality (LMI). The simulation results show that the designed controller can achieve a better control effect to achieve stability for the nonlinear time-delay systems with uncertainties and external disturbances.
