Data-driven methods for operational modal parameters identification: A comparison and application
TL;DR: A one-to-one mapping between the mathematical model of four statistical learning algorithms and physical model of dynamic systems is established and shows that the SOBI algorithm has better performance than other algorithms, and it is more suitable for operational modal identification.

Influence of Noise in Correlation Function Estimates for Operational Modal Analysis
Esben Orlowitz,Anders Brandt +1 more
TL;DR: It is shown how effects of measurement noise can be avoided by ignoring the first part of the CFs when estimating the modal parameters, and how to add noise to simulated data, so that it resembles a real-life scenario.

Reference-based stochastic subspace identification for output-only modal analysis
Bart Peeters,Guido De Roeck +1 more
TL;DR: In this paper, a novel approach of stochastic subspace identification is presented that incorporates the idea of the reference sensors already in the identification step: the row space of future outputs is projected into the rowspace of past reference outputs.
The Natural Excitation Technique (NExT) for modal parameter extraction from operating wind turbines
TL;DR: The Natural Excitation Technique (NExT) is a method of modal testing that allows structures to be tested in their ambient environments as mentioned in this paper, and has been used extensively in the literature.
