| Abstract: |
| In this paper, we investigate the passivity problem for a class of network control system with time-varying delays and nonlinear perturbations. Using the Lyapunov stability theory, together with the linear matrix inequality(LMI) technique, the sufficient conditions of passivity for the nonlinear network control system with time-varying delays, which two different cases of time delays are taken into account, are given. Finally, a numerical example with simulations shows the correction of the results and the effectiveness of the proposed method. |
