A New Maximum Likelihood Estimator Formulated in Pole-Residue Modal Model
Applied Sciences, 2019 Recently, a lot of efforts have been devoted to developing more precise Modal Parameter Estimation (MPE) techniques. This is explained by the necessity in civil, mechanical and aerospace engineering of obtaining accurate estimates for the modal ...

On the use of Continuous Wavelet Analysis for Modal Identification [PDF]
, 2006 This paper reviews two different uses of the continuous wavelet transform for modal identification purposes. The properties of the wavelet transform, mainly energetic, allow to emphasize or filter the main information within measured signals and thus facilitate the modal parameter identification especially when mechanical systems exhibit modal coupling

OUTPUT-ONLY MODAL IDENTIFICATION OF TENSEGRITY STRUCTURES
Engineering Structures and Technologies, 2016 Tensegrity systems are a special class of spatial reticulated structures that are composed of struts in compression and cables in tension. In this paper, the performance of stochastic subspace algorithms for modal identification of complex tensegrity systems is investigated.
