About McTAO team

McTAO (Mathematics for Control, Transport and their ApplicatiOns) is an Inria Team, common with Université Côte d’Azur & CNRS (Laboratoire J. A. Dieudonné) and in an agreement with Université de Bourgogne Franche-Comté & CNRS (Institut de Mathématiques de Bourgogne).  Members are located in Sophia Antipolis, Nice and Dijon.

Overall Objectives

Our goal is to develop methods in geometric control theory for nonlinear systems, mostly finite dimensional, and to transfer our expertise through real applications of these methods. The methodological developments range from feedback control and observers to optimal control, extending to fields like sub-Riemannian geometry. Optimal control leads to developments in Hamiltonian dynamics, and also requires sophisticated numerics, to which the team contributes too. Dynamical systems and modeling are also part of the background of the team.

Our primary domain of industrial applications in the past years has been space engineering, in particular using optimal control and stabilization techniques for mission design with low thrust propulsion: orbit transfer or rendez-vous problems in the gravity field of a single body (typically satellites around the earth), interplanetary missions and multi body problems, or control design of solar sails, where propulsion is drastically constrained.

The team also has continued involvement with applications regarding human bio-mechanics (muscle stimulation), and various modeling and control questions in biology (Lotka-Volterra models, bacterial growth, microbiome models, networks of chemical reaction…). The list is not exhaustive; past domains of application include swimming al low Reynolds number (micro-swimmers) and control of quantum systems for Magnetic Resonance Imaging.

Séminaire McTAO : Andrei Agrachev (SISSA, Trieste) – 15 avril 2025

Control of diffeomorphisms Andrei Agrachev (SISSA, Trieste) Mardi 15 avril, 11h00, salle Coriolis (Galois). Abstract. I am going to discuss approximate controllability and motion planning on the groups of diffeomorphisms.This work is motivated by the interpretation of artificial neural networks as input-output maps of special control problems.

Séminaire McTAO : Samuel Hornus (Centre Inria de l’Université de Lorraine) – 27 février 2025

Structure of the “Powered Descent Landing” with state and control constraints Samuel Hornus (Centre Inria de l’Université de Lorraine) Jeudi 27 février, 14h30, salle Coriolis (Galois). Abstract. The “Powered Descent Landing” problem is used for studying the last phase of landing with rocket propulsion. The goal is to land a lander at the origin, with …
