Modal parameters can accurately characterize the structural dynamic properties and assess
the physical state of the structure. Therefore, it is particularly significant to identify the …

Structural modal parameter identification is the initial step in modeling, monitoring and
controlling dynamic systems, which can determine the accuracy of dynamics and control …

In recent years, wireless sensors have progressively supplanted conventional limited
sensors owing to their attributes of small size, low cost, and high accuracy. Consequently …

In the conventional frequency domain modal identification procedures, modal parameters
are attempted to be identified using power spectral density matrix decomposition. As it is …

Blind source separation (BSS) has been demonstrated to be a promising method for
operational modal analysis (OMA). However, the conventional BSS-based modal …
