Data-driven modeling and control of large-scale dynamical systems in the Loewner framework

Ion Victor Gosea, Charles Poussot-Vassal, Athanasios C. Antoulas

In this contribution, we discuss the modeling and model reduction framework known as the Loewner framework. This is a data-driven approach, applicable to large-scale systems, which…

Reduced-order modeling of LPV systems in the Loewner framework

Ion Victor Gosea, Mihaly Petreczky, Athanasios C. Antoulas

We propose a model reduction method for LPV systems. We consider LPV state-space representations with an affine dependence on the scheduling variables. The main idea behind the pro…

Factorization of the Loewner matrix pencil and its consequences

Qiang Zhang, Ion Victor Gosea, Athanasios C. Antoulas

This paper starts by deriving a factorization of the Loewner matrix pencil that appears in the data-driven modeling approach known as the Loewner framework and explores its consequ…

Learning reduced-order models of quadratic control systems from input-output data

Ion Victor Gosea, Dimitrios S. Karachalios, Athanasios C. Antoulas

In this paper, we address an extension of the Loewner framework for learning quadratic control systems from input-output data. The proposed method first constructs a reduced-order…

On Loewner data-driven control for infinite-dimensional systems

Ion Victor Gosea, Charles Poussot-Vassal, Athanasios C. Antoulas

In this paper, we address extensions of the Loewner Data-Driven Control (L-DDC) methodology. First, this approach is extended by incorporating two alternative approximation methods…

Rational approximation of the absolute value function from measurements: a numerical study of recent methods

Ion Victor Gosea, Athanasios C. Antoulas

In this work, we propose an extensive numerical study on approximating the absolute value function. The methods presented in this paper compute approximants in the form of rational…
