摘要

随着货运列车速度和运力的提高，列车运行的安全性、能效和智能化运营变得越来越重要。货运列车自动运行可以用自动化控制系统取代人工操作，保证列车运行的安全，提高运营效率，降低运营能耗。解决货运列车由于信息多而导致跟踪精度和稳定性下降的问题。选择全球导航卫星系统、惯性导航系统和测速电机，采用松耦合组合导航和改进的熵权法构建速度融合测量模型。计算性能指标的信息量和预览控制中的控制量，得到信息融合最优预览控制的控制量。多源信息融合预览控制器的平均跟踪误差为0.038m/s，比对照实验低49%。多源信息融合预览控制器可以有效降低货物列车速度跟踪系统的跟踪误差，提高货物列车自动运行的精度。

Research on information fusion preview control for freight train speed tracking

With the increase in the speed and capacity of freight trains, the safety, energy efficiency and intelligent operation of train operation have become increasingly important. Automatic freight trains operation can replace manual operation with automated control systems, which can guarantee the safety of train operation, and improve operational efficiency and reduce operational energy consumption. Solve the problem of tracking accuracy and stability deterioration caused by multi-information of freight train. Global navigation satellite system, inertial navigation system and speed measuring motor are selected to construct a speed fusion measurement model by using loosely coupled integrated navigation and improved entropy weight method. Calculate the information quantity of performance index and control quantity in preview control, get the controlled quantity of information fusion optimal preview control. The average tracking error of the multi-source information fusion preview controller is 0.038m/s, which is 49% lower than that of the control experiment. Multi-source information fusion preview controller can effectively reduce the tracking error of freight train speed tracking system and improve the accuracy of automatic freight trains operation.
