A large number of research studies in structural health monitoring (SHM) have presented,
extended, and used subspace system identification. However, there is a lack of research on …

For the last decades vibration based damage detection of engineering structures has
become an important issue for maintenance operations on transport infrastructure. Research …

Stochastic Subspace Identification methods have been extensively used for the modal
analysis of mechanical, civil or aeronautical structures for the last ten years. So-called …

In operational modal analysis, the modal parameters (natural frequencies, damping ratios
and mode shapes), obtained with stochastic subspace identification from ambient vibration …

The modes of linear time invariant mechanical systems can be estimated from output-only
vibration measurements under ambient excitation conditions with subspace-based system …

The uncertainty afflicting modal parameter estimates stems from eg, the finite data length,
unknown, or partly measured inputs and the choice of the identification algorithm …

An important step in the operational modal analysis of a structure is to infer on its dynamic
behavior through its modal parameters. They can be estimated by various modal …

Subspace methods have proven to be efficient for the identification of linear time-invariant
systems, especially applied to mechanical, civil or aeronautical structures in operation …

The transfer function of a linear mechanical system can be defined in terms of the quadruplet
of state-space matrices (A, B, C, D) that can be identified from input and output …
