The non-fragile H_∞ control problem is studied for the uncertain nonlinear network switching system with random time-varying delay and data packet dropout, in which the controller gain exists perturbation. Firstly, based on the T-S model, the nonlinear network switching system is modeled as a network switch fuzzy system. Then, the packet loss is treated as a time delay, and the time delay is described by the random sequence of Bernoulli distributed. By using the average dwell time(ADT) method, the system switching law and the non-fragile state feedback controller are designed, and the ADT condition of the exponential stability for the network switched fuzzy system is presented. Finally, by combining with Lyapunov(LKF) method, a sufficient condition for the mean square exponential of system stable and satisfying the performance criterion of H_∞ is presented. A Matlab numerical simulation verifies the effectiveness of the designed method.
