We propose an observer design method for nonlinear network systems. First, the observer design for the systems without external disturbance is considered, and the systems with uncertain external disturbance. A sufficient condition is given for the existence of such an observer in terms of linear matrix inequality (LMI). Then the stability and robustness of the proposed control scheme are then validated for different network scenarios in MATLAB. Simulation results have confirmed that the feasibility of the presented method.
