Learning a Contracting KKL-observer with Local Optimal Guarantees
Clara LucÃa Galimberti, Johan Peralez, Daniele Astolfi +2
The Kazantzis-Kravaris-Luenberger (KKL) observer provides a general framework for nonlinear state estimation by immersing the system dynamics into a stable linear or nonlinear late…
Proximal observers for secure state estimation
Laurent Bako, Madiha Nadri, Vincent Andrieu +1
This paper discusses a general framework for designing robust state estimators for a class of discrete-time nonlinear systems. We consider systems that may be impacted by impulsive…
Edges' Riemannian energy analysis for synchronization of multi-agent nonlinear systems over undirected weighted graphs
Vincent Andrieu, Daniele Astolfi, Alexandre Cellier-Devaux
In this note we investigate the problem of global exponential synchronization of multi-agent systems described by nonlinear input affine dynamics. We consider the case of networks…
Generalized Lyapunov conditions for k-contraction: analysis and feedback design
Andreu Cecilia, Samuele Zoboli, Daniele Astolfi +2
Recently, the concept of k-contraction has been introduced as a promising generalization of contraction for dynamical systems. However, the study of k-contraction properties has fa…
