| 摘 要： | 交通控制的实时性要求高,需要实时快速判定交通流混沌才可以实现交通流的混沌控制。由于在一个控制周期内只能获得很少量数据,交通流时间序列的样本数受到限制。然而现有的混沌识别方法由于要求样本量大,无法满足实时性要求。基于GM(1,1)模型的混沌特性提出一种新的实时快速识别交通流混沌的方法,可以在混沌之初检测到混沌。并通过理论交通流时间序列、实测交通流时间序列进行了实证分析。结果表明:只需至少4个样本点就可以在混沌产生之初精确地检测到混沌,可以很好地满足混沌检测实时性的要求。

| Abstract: | On-line traffic control has high real time requirement.It needs to identify the chaos in traffic flow on-line and rapidly realize chaotic control of traffic flow.In a control cycle,only quite a few data can be obtained so that the number of samples for time series of traffic flows is restricted.But the existing identifying method cannot fit this requirement because it needs a large number of samples.A novel method for real-time rapid identification of the chaos in traffic flow is presented based on chaotic ... |
