Reinforcement Twinning for Hybrid Control of Flapping-Wing Drones
Romain Poletti, Lorenzo Schena, Lilla Koloszar +2
Controlling flapping-wing drones requires controllers that handle time-varying, nonlinear, underactuated dynamics from incomplete, noisy sensor data. Recent advances in artificial…
A Fast Spectral Formulation of the Multiscale Proper Orthogonal Decomposition
Marek Belda, Lorenzo Schena, Romain Poletti +3
Multiscale Proper Orthogonal Decomposition (mPOD) decomposes fluid flows into energy-optimal modes within prescribed frequency bands by combining Proper Orthogonal Decomposition wi…
Learning with Physical Constraints
Miguel A. Mendez, Jan van Den Berghe, Manuel Ratz +2
This chapter provides three tutorial exercises on physics-constrained regression. These are implemented as toy problems that seek to mimic grand challenges in (1) the super-resolut…
Unisingular representations of rank 1 finite simple groups of Lie type
Marco Antonio Pellegrini, Lorenzo Schena
A representation of a finite group is called unisingular if the matrix admits as an eigenvalue for any . In this paper…
Nonlinear System Identification for Model-Based Control of Waked Wind Turbines
Sebastiano Randino, Lorenzo Schena, Nicolas Coudou +2
This work presents a nonlinear system identification framework for modeling the power extraction dynamics of wind turbines, including both freestream and waked conditions. The appr…
POD-Based Sparse Stochastic Estimation of Wind Turbine Blade Vibrations
Lorenzo Schena, Wim Munters, Jan Helsen +1
This study presents a framework for estimating the full vibrational state of wind turbine blades from sparse deflection measurements. The identification is performed in a reduced-o…
