Global Convergence of Control-Based Lagrangian Flows for Non-Convex Optimization
Simone Pirrera, Francesco Ripa, Daniele Astolfi +3
This paper studies the continuous-time dynamics generated by control-theoretic Lagrangian methods for equality-constrained optimization. In particular, we consider dynamics induced…
On the Solvability of Quasi-Regulator Equations in Non-smooth Output Regulation
Zirui Niu, Daniele Astolfi, Giordano Scarciotti
Motivated by the prevalence of non-smooth, possibly non-periodic signals in real-world applications, the output regulation of linear systems subject to non-smooth non-periodic exog…
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…
A Nonlinear Incremental Approach for Replay Attack Detection
Tao Chen, Andreu Cecilia, Lei Wang +2
Replay attacks comprise replaying previously recorded sensor measurements and injecting malicious signals into a physical plant, causing great damage to cyber-physical systems. Rep…
Integral action for bilinear systems with application to counter current heat exchanger
Francesco Ripa, Daniele Astolfi, Boussad Hamroun +1
In this study, we propose a robust control strategy for a counter-current heat exchanger. The primary objective is to regulate the outlet temperature of one fluid stream by manipul…
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…
