Resumen

In this paper, novel hybrid methodologies for modal parameters extraction using Empirical Mode Decomposition (EMD) based techniques combined with classic signal processing spectral analysis are presented. The modal frequencies are extracted by a methodology that combines EMD and Fast Fourier Transform (FFT). The damping factor is obtained by another methodology that uses FFT as a time-frequency estimator. The proposed methodologies were applied to real signals. Results have shown very good accuracy, precision, and low dispersion in comparison with other conventional methods.
