列车运行控制系统是保证列车安全、高速和高效运行的重要设备,根据列车在铁路线路上运行的客观条件和实际情况,对列车运行速度进行监督、控制和调整。高速、舒适是世界铁路发展的主要目标和方向,开发高效的高速列车运行控制系统势在必行。本文首先分析高速列车运行的控制问题,建立了高速列车运行的动力学模型,以给定的牵引和制动特性曲线得到参考速度曲线,将模糊控制技术应用于列车的运行控制中,实现了高速列车运行速度的智能控制。在Simulink中进行仿真研究,仿真结果表明,采用模糊控制的控制系统能确保列车实际运行速度很好地跟踪给定速度,系统的鲁棒性良好。

Research on Operation Control System of High-speed Train Based on Fuzzy Control

Train operation control system,an important device to ensure safety,high-speed and efficiency in train operation,supervises the speed of train according to the practical situations when running on the rail.High-speed and comfort are the main targets and orientations in the development of world rail,so it＇s inevitable to develop an efficient operation control system.The problem of operation control of high-speed train was analyzed,and,a dynamic model of high-speed train operation was built in this paper.Fuzzy control was applied to control the train＇s operation,which realized the intelligent velocity control of high-speed train referred to traction and braking performance curves.Several simulations basing on Simulink were made,and the results show that the train＇s actual velocity can match up to the reference speed tightly and the system has a robustness performance by the effect of fuzzy control.
