System identification at ESAT-STADIUS
SCD-STADIUS is a research group of the electrical engineering
department of the Katholieke Universiteit Leuven, Belgium. On this
site we give an overview of system identification related research at
SISTA. Where available, preprints of our
papers and related software can be downloaded
from the site.
The aim of system identification is to construct models from data. Two popular approaches are prediction error minimization and subspace identification. Our research group is well-known for the development of subspace identification algorithms. Predictor error methods are based on local optimization algorithms, while subspace methods are based on geometric operations on subspaces spanned by matrices obtained from data and do not involve explicit optimization criteria. Hence, in general, subspace methods are fast and reliable, however, less accurate than the computationally heavier prediction error methods.
