10h00-11h00 – Salle du conseil (L2S) Output regulation for infinite-dimensional systems: A forwarding-based approach Nicolas Vanspranghe (GIPSA-lab) Abstract. The output regulation problem for infinite-dimensional nonlinear systems is considered. In particular, we allow the output operator to be unbounded, which is the case in boundary control problems, and we assume the original dynamics to be a […]
11h00-12h00 – Salle du conseil (L2S) Minimal 2-spheres in ellipsoids via global bifurcation theory Paolo Piccione (Universidade de São Paulo, Brazil) Abstract. I will give an overview of classical results in variational Bifurcation Theory, present some applications to geometric variational problems, and discuss a concrete problem concerning the multiplicity of minimal 2-spheres inside sufficiently elongated […]
11/05/2021 – 16h30-17h30 – Online Federated stochastic control of numerous heterogeneous energy storage systems Emmanuel Gobet (CMAP, École Polytechnique, Palaiseau) Abstract. We propose a stochastic control problem to control cooperatively Thermostatically Controlled Loads (TCLs) to promote power balance in electricity networks. We develop a method to solve this stochastic control problem with a decentralized architecture, […]
06/04/2021 – 14h00-15h00 – Online Dynamics of continuum and soft robots: a strain parametrization based approach Frédéric Boyer (LS2N, IMT-Atlantique, Nantes) Abstract. In this seminar we propose a new dynamic model of Cosserat beams in view of its application to continuum and soft robotics manipulation and locomotion. In contrast to usual approaches, it is based […]
23/03/2021 – 14h00-15h00 – Online Control and Feedback stabilization for entropy solutions to conservation laws Vincent Perrollaz (IDS, Université de Tours) Abstract. Hyperbolic conservation laws are partial differential equations that are used to model many kind of physical phenomena: gas dynamics, traffic flow, electromagnetism, shallow water theory, combustion theory… However even the simplest equation of […]
