Identification of low-order models using Laguerre basis function expansions

M Manngård, HT Toivonen - IFAC-PapersOnLine, 2018 - Elsevier
In this paper, a method for identification of low-order output-error models expressed in terms
of Laguerre basis functions is presented. The identification problem is formulated as a rank …

On nuclear norm minimization in system identification

N Blomberg - 2016 - diva-portal.org
In system identification we model dynamical systems from measured data. This data-driven
approach to modelling is useful since many real-world systems are difficult to model with …

Non-Parametric Bayesian Methods for Linear System Identification

G Prando - 2017 - research.unipd.it
Recent contributions have tackled the linear system identification problem by means of non-
parametric Bayesian methods, which are built on largely adopted machine learning …

An analysis of the SPARSEVA estimate for the finite sample data case

H Ha, JS Welsh, CR Rojas, B Wahlberg - Automatica, 2018 - Elsevier
In this paper, we develop an upper bound for the SPARSEVA (SPARSe Estimation based on
a VAlidation criterion) estimation error in a general scheme, ie, when the cost function is …

A branch and bound approach to system identification based on fixed-rank hankel matrix optimization

M Sadeghi, CR Rojas, B Wahlberg - IFAC-PapersOnLine, 2018 - Elsevier
We consider identification of linear systems with a certain order from a set of noisy input-
output observations. We utilize the fact that the system order corresponds to the rank of the …

Identification of low-order models using rational orthonormal basis functions

M Manngård, HT Toivonen - 2019 IEEE 58th Conference on …, 2019 - ieeexplore.ieee.org
A method for complexity constrained output-error system identification using rational
orthonormal basis functions is presented. The model is expanded in terms of a Hambo …
