TLDR
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.About:

Temperature measurement assisted modal tracking of an instrumented building
TL;DR: This study tries to overcome this limitation on the tracking component of SHM with the aid of a predictive numerical model based on the effect of the ambient temperature on the modal frequency, and validates the simpler temperature – frequency model.
Frequency Domain versus Time Domain Modal Identifications for Ambient Excited Structures
TL;DR: In this article, the authors present theoretical backgrounds of the most modern and recent modal identification methods in the frequency domain and in the time domain such as Frequency Domain Decomposition (FDD) and Stochastic Subspace Identification (SSI).

Exploring vibration control strategies for a footbridge with time-varying modal parameters
TL;DR: In this article, the authors explored different vibration control strategies for the cancellation of human-induced vibration of a structure with time-varying modal parameters, and designed three control strategies: a tuned mass damper (TMD) tuned to the aforementioned mode using its most-repeated modal properties, a semi-active TMD with an on-off control law for the TMD damping, and an active MMD designed using the well-known velocity feedback control strategy with a saturation nonlinearity.
