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 command 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 negative 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 command system.
