- 免费试用版奇异熵矩阵束模态辨识软件 信号模态辨识在电力系统振荡和机械振荡中都有广泛的应用,传统的分析方法主要基于Prony算法,由于是强制性的指数多项式拟合,对信号模态的辨识性能不是很好,特别是一些集成辨识工具无法对模态阶数进行设置。prony算法、itd算法、arma算法和HHT方法对信号噪声敏感。-good
(HHT)Hilbert-HuangTransform
- The Hilbert–Huang transform (HHT)is an empirically based data-analysis method. Its basis of expansion is adaptive, so that it can produce physically meaningful representations of data from nonlinear and non-stationary processes.
emd
- 对一时间序列进行EMD分解,产生若干经验模态。是HHT变换的前提。-EMD of a time series decomposition, resulting in a number of empirical mode,which is a prerequisite for HHT transformation.
