摘要
很多非线性系统的外部特性通常只能是某个单变量的时间序列.采用延迟坐标状态空间这种相空间重构方法,对非线性系统中的单一时间序列进行分析,从中恢复出系统内部存在的非线性动力学特性.对两个关键参数的选择做了大量的理论分析研究.用某些经典的混沌系统对这些算法进行了验证,结果表明程序计算的实际值和理论值基本一致.
The external characteristic of many non-linear systems is only a certain fonn time series of variable usually. The delay-coordinate method is adopted to reconstructed the space phase, and to analyze the single time series in the non-linear systems and resume the nonlinear kinetics characteristics. The A large number of theory analysis are made and research which can chose the two keys-parameters. Some classical chaotic systems are used to check formula, the result indicate the values calculated by the programs accord with the theory values.
