There will be time-delay in the process of monitoring data transmission on the train coupling communication network. The network time-delay can deteriorate the coupling control performance. In order to solve this problem, simplified model of networked control system was established with respect to coupling EMU. The time-delay auto regressive (AR) model was established, and Yule-walker parameter self-identification algorithm was used for time-delay online prediction according to historical data. At the same time, fast implicit generalized prediction control was used for compensating predictive time-delay. Simulation results show that this method has high prediction accuracy, a good effect on time-delay compensation and can ensure the good control effect %K 动车组 %K 重联网络控制 %K UIC网关 %K 时延预测 %K 隐式广义预测控制< %K br> %K EMU %K coupling network control %K UIC gateway %K time-delay prediction %K implicit generalized predictive control %U http://www.jrse.cn/paper/paperView.aspx?id=paper_318843
