This paper aims to enhance the efficiency of validation and verification campaigns involving fuel sloshing phenomena. Our first contribution is the development of an open-source, h…
Learning Surrogate LPV State-Space Models with Uncertainty Quantification
E. Javier Olucha, Valentin Preda, Amritam Das +1
The Linear Parameter-Varying (LPV) framework enables the construction of surrogate models of complex nonlinear and high-dimensional systems, facilitating efficient stability and pe…
Amplitude Dependent Bode Diagrams via Scaled Relative Graphs
Julius P. J. Krebbekx, Roland Tóth, Roland Tóth +2
Scaled Relative Graphs (SRGs) provide an intuitive graphical frequency-domain method for the analysis of Nonlinear (NL) systems, generalizing the Nyquist diagram. In this paper, we…
Bayesian Optimization Based Grid Point Allocation for LPV and Robust Control
E. Javier Olucha, Arash Sadeghzadeh, Amritam Das +1
This paper investigates systematic selection of optimal grid points for grid-based Linear Parameter-Varying (LPV) and robust controller synthesis. In both settings, the objective i…
Computing the Hard Scaled Relative Graph of LTI Systems
Julius P. J. Krebbekx, Eder Baron-Prada, Roland Tóth +1
Scaled Relative Graphs (SRGs) provide a novel graphical frequency-domain method for the analysis of nonlinear systems, where Linear Time-Invariant (LTI) systems are the fundamental…
