预测控制方法在列车速度控制中的应用

随着我国铁路建设的高速发展，列车运行速度不断提高，行车密度不断加大，原有的列车速度控制方法难以满足安全行车要求。本文研究了列车速度的预测控制方法。设计了列车预测控制策略，对列车运行速度进行实时预测及优化。针对列车速度的预测控制策略设计了系统仿真程序并进行了系统仿真，结果表明，采用预测控制可以根据以后的输入对列车速度和控制策略进行有计划的调整，提高了列车速度的控制效果和控制效率，利用在线估计预测模型，采用在线滚动优化和反馈校正策略，减少了由于模型不准确带来的误差。

The Application of Predictive Control Method in Train Speed Control

With the high-speed development of railway construction, the continuous increasing of train speed, and the unceasing enhancement of the train＇s running density, the original train speed control methods are difficult to meet the security requirements. The method of train speed predictive control is studied in this paper. The train predictive control strategy is designed to optimize and predict the train＇s running speeds on real-time. In view of the train speed predictive control strategy, the simulation program is designed and carried out. The simulation result shows that predict control could adjust the train speed and control method according to the input. The control effect and efficiency of the train speed can be obviously enhanced. Using online estimate predict model, online trundle optimize and feed back adjustment strategy, the error caused by the incorrect model is reduced.
