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…
Temporal Graph Neural Networks for Early Anomaly Detection and Performance Prediction via PV System Monitoring Data
Srijani Mukherjee, Laurent Vuillon, Liliane Bou Nassif +4
The rapid growth of solar photovoltaic (PV) systems necessitates advanced methods for performance monitoring and anomaly detection to ensure optimal operation. In this study, we pr…
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…
Oxysterols in Vascular Cells and Role in Atherosclerosis
Celine Luquain-Costaz, Isabelle Delton
Atherosclerosis is a major cardiovascular complication of diseases associated with elevated oxidative stress such as type 2 diabetes and metabolic syndrome. In these situations, lo…
Necessary and sufficient condition for neutral-type delay systems: Polynomial approximations
Gerson Portilla, Mathieu Bajodek, Sabine Mondié
A new necessary and sufficient stability test in a tractable number of operations for linear neutral-type delay systems is introduced. It is developed in the Lyapunov-Krasovskii fr…
Integral action feedback design for conservative abstract systems in the presence of input nonlinearities
Ling Ma, Vincent Andrieu, Daniele Astolfi +3
In this article, we present a stabilization feedback law with integral action for conservative abstract linear systems subjected to actuator nonlinearity. Based on the designed con…
Output feedback stabilisation of bilinear systems via control templates
Ludovic Sacchelli, Lucas Brivadis, Ulysse Serres +1
We establish a separation principle for the output feedback stabilisation of state-affine systems that are observable at the stabilization target. Relying on control templates (rec…
On the existence of KKL observers with nonlinear contracting dynamics (Long Version)
Victor Pachy, Vincent Andrieu, Pauline Bernard +2
KKL (Kazantzis-Kravaris/Luenberger) observers are based on the idea of immersing a given nonlinear system into a target system that is a linear stable filter of the measured output…
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…
State estimation of an electrochemical lithium-ion battery model: improved observer performance by hybrid redesign
E. Petri, T. Reynaudo, R. Postoyan +3
Effective management and just-in-time maintenance of lithium-ion batteries require the knowledge of unmeasured (internal) variables that need to be estimated. Observers are thus de…
Eagle: Large-Scale Learning of Turbulent Fluid Dynamics with Mesh Transformers
Steeven Janny, Aurélien Béneteau, Madiha Nadri +3
Estimating fluid dynamics is classically done through the simulation and integration of numerical models solving the Navier-Stokes equations, which is computationally complex and t…
Forwarding-Lyapunov design for the stabilization of coupled ODEs and exponentially stable PDEs
Swann Marx, Daniele Astolfi, Vincent Andrieu
This paper is about the stabilization of a cascade system composed by an infinite-dimensional system, that we suppose to be exponentially stable, and an ordinary differential equat…
Supervising the Transfer of Reasoning Patterns in VQA
Corentin Kervadec, Christian Wolf, Grigory Antipov +2
Methods for Visual Question Anwering (VQA) are notorious for leveraging dataset biases rather than performing reasoning, hindering generalization. It has been recently shown that b…
Approximate observability and back and forth observer of a PDE model of crystallisation process
Lucas Brivadis, Ludovic Sacchelli
In this paper, we are interested in the estimation of Particle Size Distributions (PSDs) during a batch crystallization process in which particles of two different shapes coexist a…
Deep KKL: Data-driven Output Prediction for Non-Linear Systems
Steeven Janny, Vincent Andrieu, Madiha Nadri +1
We address the problem of output prediction, ie. designing a model for autonomous nonlinear systems capable of forecasting their future observations. We first define a general fram…
Forwarding design for stabilization of a coupled transport equation-ODE with a cone-bounded input nonlinearity
Swann Marx, Lucas Brivadis, Daniele Astolfi
We propose a new design technique for the stabilization of coupled ODE-PDE systems in feedforward form. In particular, we address the stabilization problem of a one-dimensional tra…
New dynamical observer for a batch crystallization process based on solute concentration
Vincent Andrieu, Emilie Gagnière, Elodie Chabanon +4
In this paper a new observer is introduced to estimate the Crystal Size Distribution (CSD) only from the measurements of the solute concentration, temperature and a model of the gr…
From local to global asymptotic stabilizability for weakly contractive control systems
Vincent Andrieu, Lucas Brivadis, Jean-Paul Gauthier +2
A nonlinear control system is said to be weakly contractive in the control if the flow that it generates is non-expanding (in the sense that the distance between two trajectories i…
Luenberger observers for infinite-dimensional systems, Back and Forth Nudging and application to a crystallization process
Lucas Brivadis, Vincent Andrieu, Ulysse Serres +1
This paper deals with the observer design problem for time-varying linear infinite-dimensional systems. We address both the problem of online estimation of the state of the system…
