Data-driven Output Regulation via Gaussian Processes and Luenberger Internal Models

no code implementations28 Oct 2022 Lorenzo Gentilini, Michelangelo Bin, Lorenzo Marconi

This paper deals with the problem of adaptive output regulation for multivariable nonlinear systems by presenting a learning-based adaptive internal model-based design strategy.

Data-Driven Analytic Differentiation via High Gain Observers and Gaussian Process Priors

no code implementations27 Oct 2022 Biagio Trimarchi, Lorenzo Gentilini, Fabrizio Schiano, Lorenzo Marconi

The presented paper tackles the problem of modeling an unknown function, and its first $r-1$ derivatives, out of scattered and poor-quality data.

Output Regulation by Postprocessing Internal Models for a Class of Multivariable Nonlinear Systems

no code implementations24 Nov 2021 Michelangelo Bin, Lorenzo Marconi

In this paper we propose a new design paradigm, which employing a postprocessing internal model unit, to approach the problem of output regulation for a class of multivariable minimum-phase nonlinear systems possessing a partial normal form.

Nonlinear Robust Periodic Output Regulation of Minimum Phase Systems

no code implementations14 Sep 2021 Daniele Astolfi, Laurent Praly, Lorenzo Marconi, Mines Paristech

In linear systems theory it's a well known fact that a regulator given by the cascade of an oscillatory dynamics, driven by some regulated variables, and of a stabiliser stabilising the cascade of the plant and of the oscillators has the ability of blocking on the steady state of the regulated variables any harmonics matched with the ones of the oscillators.
