26 février 2026 @ 14h00 – 15h00 – Lien visio : Teams Titre : Between servo regulation and agreement: the consensus protocol revisited Résumé : It can be argued that control theory emerged from three engineering objectives: i) stabilize a system, ii) reject unwanted external signals, and iii) minimize the effects of uncertainty. This is the core of the classic servo-regulation problem, where controllers […]
12 mars 2026 @ 14h00 – 15h00 – Lien visio : Teams Titre : Structure, Analysis, and Synthesis of First-Order Algorithms Résumé : Optimization algorithms can be interpreted through the lens of dynamical systems as the interconnection of a linear system and a set of subgradient nonlinearities. This dynamical systems formulation allows for the analysis and synthesis of optimization algorithms by solving robust control problems. In […]
28 mai 2026 @ 14h00 – 15h00 – Titre : Promoting Social Change Through a Network Co-Evolutionary Model Résumé : Complex social systems are characterized by a deep intertwining between opinion formation and decision-making processes. However, these two processes have been typically studied as separate problems in the literature, limiting the possibility to capture and study the complexity of real-world social systems. This […]
4 juin 2026 @ 14h00 – 15h00 – Titre : Consensus Control of Microgrids via Krasovskii Passivity Résumé : Several problems in power systems can be formulated as consensus problems, including current/power sharing in DC microgrids and input allocation in swing equations. To address these problems, we propose a new passivity concept named Krasovskii passivity. We show that DC microgrids with buck converters and AC […]
