| 摘 要： | 在对纱条不匀序列进行相空间重构的基础上,通过G-P算法,分析了关联维数的饱和特性,得到其吸引子的分数维,其次又采用了PCA分布法对其进行确认,结果表明在所分析的棉条不匀序列中,存在混沌现象.这为进一步应用混沌理论对纱条不匀进行分析和建模奠定了理论基础. |
| 关 键 词： | 纱条不匀 相空间重构 自相关函数 关联维数 主分量 |

| Abstract: | In this paper, the chaotic phenomenon in terms of the observation time series of yarn evenness is studied. On the base of phase space reconstruction, both G-P algorithm and PCA method are adopted to extract its chaotic character. The result shows that chaos exists in the series of yarn evenness which exhibit very different character from white noise series. |
| Keywords: | sliver evenness phase space reconstruction correlation dimension correlation dimension PCA |
