12 septembre 2024 @ 14h00 – 15h00 – Titre : Guaranteed ellipsoidal numerical method for the stability analysis of the formation control of a group of underwater robots. Résumé : Various theoretical controllers have been proposed to make underwater robots move in a formation to make the group’s behaviour more reliable. As for every autonomous system, stability analysis is one step of a controller’s […]

13 septembre 2024 @ 14h00 – 15h00 – The passivity of singularly perturbed systems (SPSs) is generally studied without taking advantage of the time-scale separation present in this class of systems. This objective of the presentation is to provide easy-to-verify well-posed conditions characterizing the passivity of a linear SPS starting from the passivity of its associated reduced-order system. To achieve this goal, one […]

14 novembre 2024 @ 14h00 – 15h00 – Titre : Stabilisation rapide d’une classe d’EDP non linéaires : Application à l’équation de Vlasov-Poisson. Abstract : Cet exposé abordera la stabilisation d’un modèle discrétisé de l’équation de Vlasov-Poisson, qui décrit l’évolution spatio-temporelle d’une fonction de distribution de particules chargées dans un plasma. Dans un premier temps, j’étudierai la stabilisation en temps fixe de ce type […]

23 janvier 2025 @ 14h00 – 16h00 – Titre : System theory tools for optimization and learning in complex and distributed systems – Résumé : In this talk I will address control and learning scenarios requiring the online solution of (possibly distributed) optimization problems. I will first highlight some key challenges arising in addressing these problems as, e.g., online and closed-loop nature of […]

30 janvier 2025 @ 14h00 – 15h00 – Title: Nonlinear motion control. Abstract: Traditionally, high-tech motion systems are controlled by PID-control, despite the fact that these PID designs, or more generally speaking any linear time-invariant control design, is subject to fundamental performance limitations. It was already observed in the 1950’s that introducing reset and switching mechanisms in an otherwise linear control loop can alleviate these […]

27 février 2025 @ 14h00 – 15h00 – – Lien Teams : cliquer ici. – Titre : Nanoscale control theory – Résumé : Modelling and design of interconnected nanoscale systems, such as electronic circuits or biochemical networks, call for a rewriting of the rulebook of control theory. In order to agree with fundamental laws of nature, such as microscopic reversibility and ubiquitous thermal […]

28 février 2025 @ 10h30 – 11h30 – Titre : $H_\infty$ event triggering with performance guarantees: what can we prove and what cannot (yet) – Résumé : Time-triggered (TT) sampled-data control assumes that sampling instances are generated in a process-independent fashion, normally via an external clock. Event-triggered (ET) control, in which sampling instances may be generated on the basis of the actual evolution of control and […]

4 mars 2025 @ 10h30 – 11h30 – Titre :  Internal Model Control Revisited – Résumé : By the Internal Model Principle, the asymptotic rejection of persistent exogenous signals with known patterns (constant, harmonic, periodic, etc) requires incorporating their models (integrator, harmonic oscillator, repetitive element, etc) into the feedback loop. A conventional design approach in this case is to augment the plant by […]
