关于高速铁路调度指挥系统稳定性的探讨

探讨了高速铁路调度所内调度系统的信息传递过程，采用控制论中系统方块图进行描述，计算出高铁调度系统的信息传递函数，然后求得调度系统的特征方程和特征根，通过分析特征根是否均有负实部来判断系统的稳定性。提出了描述调度系统控制精确度的稳态误差的计算方法。为今后高速铁路调度系统的稳定性的研究有所启发。

Discussion of Stability of High-speed Railway Dispatch Command System

This article mainly discusses the message transfer process in the high-speed railway dispatch com-mand system .Using systematic block diagram in control theory , this paper figures out message transfer function about the high-speed railway dispatch command system , then work out characteristic equation and characteristic roots, and finally judge the stability of the system through the analysis of whether characteristic roots have nega -tive real part.This article also puts forward the calculation method of steady-state error for describing the control accuracy , which may be useful and inspiring to the research on the stability of high-speed railway dispatch com-mand system .
