Numerical Algorithms for Subspace State Space System Identification
Bart De Moor,Peter Van Overschee +1 more
TL;DR: The basic notions on subspace identification algorithms for linear systems first estimate a state sequence directly from input-output data, through an orthogonal or oblique projection of the row space of certain input- output block Hankel matrices into the row spaces of others.

Frequency-domain subspace identification using FRF data from arbitrary signals
TL;DR: In this paper, an extension of the frequency-domain subspace identification methods was developed that can cope with arbitrary excitation signals and transient effects, and the implications of this extended model are investigated for the H 1 estimator.

Empirical reduced-order modeling for boundary feedback flow control
TL;DR: The proper orthogonal decomposition of a high dimension system as well as frequency domain identification methods are discussed for initial model construction and Balanced truncation is used to show that model reduction is still effective on ERA produced approximated systems.

Dissipated Energy Ratio as a Feature for Earthquake-Induced Damage Detection of Instrumented Structures
Eric M. Hernandez,Geoff May +1 more
TL;DR: In this paper, an energy-based damage feature is proposed to detect the presence of earthquake-induced structural damage in instrumented buildings, where the proposed feature is a function of the ratio between the hysteretic dissipated energy and the total amount of energy.
