PASSIVE ANALYSIS FOR A CLASS OF NETWORK CONTROL SYSTEM WITH TIME-VARYING DELAY AND NONLINEAR PERTURBATION

本文研究了一类非线性时滞网络控制系统的无源性问题.利用Lyapunov稳定性理论,结合线性矩阵不等式(LMI)技术,通过构造Lyapunov-Krasovskii泛函,在考虑两种不同时滞的情况下,获得了系统满足无源性的充分条件,最后通过仿真算例验证了结论的正确性和方法的有效性.
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
