列车网络控制是列车安全行驶的保障。提出一种新的基于观测器的列车网络控制方法，同时考虑测量通道和控制通道的网络诱导延时的影响，利用增广状态向量法构建基于观测器的列车网络控制系统模型；在考虑网络诱导延时与其时滞上界关系基础上，构造 Lyapunov 泛函，导出使扩展闭环系统渐近稳定的时滞相关 LMI 充分条件；给出求解控制器和观测器增益矩阵的方法。最后，通过数值仿真算例验证了该方法的有效性和可行性。

In this paper,the new method for train network control was proposed.First,the observer -based train networked control system was modeled as a multiple delay system by the augmented state vector method,in which the network -induced delays in measurement and control channels are taken into account simultaneously. Then,by taking the relationship between the networked -induced delays and their upper bounds into full consid-eration,constructing a proper Lyapunov functional candidate and applying the integral inequality approach and the linear matrix inequality method,an improved delay -dependent LMI sufficient condition of asymptotical sta-bility for augmented closed -loop system was developed.In addition,the algorithm to calculate the controller and observer gain matrices was presented.Finally,numerical example was provided to demonstrate the feasibility and effectiveness of the proposed method.
