摘要
本文从文献[1]中所建立的多输入多输出实验模态参数识别的统一模型出发,推导出几种近十几年最常见的多输入多输出实验模态参数频域识别法,阐明了它们之间的内在联系,统一了频域识别技术的理论基础。
Abstract In this paper,some widely used multi-input and multi-output modal parameter identification methods in frequency domain are introduced on the basis of the theory called uni- fied mathematical models shown in the reference,the relation among all these methods is re- vealed and their theoretical foundation is unified.
