An Improved Method for Choosing Parameters in Phase Space Reconstruction
Author(s): 
Pages: 242-244
Year: Issue:  2
Journal: JOURNAL OF VIBRATION ENGINEERING

Keyword:  相空间重构时间延迟平均位移交叉位移;
Abstract: 阐述了时间延迟对相空间重构的影响,研究了平均位移法选择时间延迟的原理,并通过分析相空间扩展的几何意义,对平均位移法进行了改进;利用典型数据对两种方法进行测试,结果表明,改进后的方法不仅具有更明确的物理意义,而且可以更好地选择时间延迟.
