摘要: 铁路运输的不断发展,提高列车运行效率,成为铁路交通系统优化的关键目标。提出一种基于线性二次调节器(LQR)的列车协同控制方法,探究该方法在控制输入时滞的条件下实现列车协同运行的效果以提高列车运行效率,并通过仿真研究系统性评估其在列车协同控制中的应用效果。首先,通过建立多列车运行过程中追踪动力学数学模型,设计前后车误差模型作为协同控制的约束,其次,通过设计LQR控制器实现列车协同控制,最后,设计后车跟踪前车的仿真实验。结果表明,基于LQR控制的列车协同控制方法能够显著提高多列车协同运行效率。

Abstract: With the continuous development of railway transport, improving the train operation efficiency has become a key goal of railway transport system optimization. This study is intended to propose a cooperative train control method based on Linear Quadratic Regulator (LQR), explore the effects of this method on cooperative train operation under the condition of control input delay, so as to improve the train operation efficiency, and conduct systematic assessment about the application effects of this method on cooperative train control through simulation study. Firstly, a mathematical model of tracking dynamics is established for the process of multi-train running, and an error model of the preceding and following trains is designed as the constraint of cooperative control. Secondly, an LQR controller is designed for cooperative train control. Finally, simulation tests are designed for the following train tracking the preceding train. The results show that the cooperative train control method based on LQR control can significantly improve the efficiency of multi-train cooperative operation.
