本文提出一种基于相空间再构（PSR）的奇异值分解（SVD）谐波分析方法，可将信号中的谐波分量按其能量大小进行时域分解。数字模拟实验表明了该方法的有效性。利用该方法对建筑结构振动进行的隐藏频率提取和谐波分析，对于我们对建筑结构振动的控制方案的设计具有指导作用。
This paper proposes a SVD harmonic analysis method based on Phase Space Reconstruction (PSR), which can decompose the harmonic components in the signal according to their energy. Digital simulation experiments show the effectiveness of the method. The hidden frequency extraction and harmonic analysis of the vibration of the building structure using this method has a guiding role in the design of our control scheme for the vibration of the building structure.
