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…
Model reduction of linear hybrid systems
Ion Victor Gosea, Mihaly Petreczky, John Leth +2
The paper proposes a model reduction algorithm for linear hybrid systems, i.e., hybrid systems with externally induced discrete events, with linear continuous subsystems, and linea…
On Bilinear Time Domain Identification and Reduction in the Loewner Framework
D. S. Karachalios, I. V. Gosea, A. C. Antoulas
The Loewner framework-(LF) in combination with Volterra series-(VS) offers a non-intrusive approximation method that is capable of identifying bilinear models from time-domain meas…
