Loewner framework
Witryna29 cze 2024 · In this paper, we address an extension of the Loewner framework for learning quadratic dynamical systems from input-output data. The proposed method first constructs a reduced-order linear model from measurements of the classical transfer function. Then, this surrogate model is enhanced by incorporating a term that … WitrynaThe Loewner framework, originally proposed in [30] for solving the generalized realization problem coupled with tangential interpolation, was successfully employed for data-driven model order reduction from frequency domain data …

Witryna16 mar 2024 · The Loewner framework is one of the most successful data-driven model order reduction techniques. If N is the cardinality of a given data set, the so-called Loewner and shifted Loewner matrices \({\mathbb {L}}\in {\mathbb {C}}^{N\times N}\) and \({\mathbb {S}}\in {\mathbb {C}}^{N\times N}\) can be defined by solely relying on … Witryna1 kwi 2016 · As a consequence this approach yields transfer functions for singular and rectangular systems.
