    Séminaire LARIS - Nicolas DELANOUE et Vinicius Mariano GONÇALVES

    à partir de 14h00 en salle du conseil de l'ISTIA

    Le 7 juillet 2015

    Nicolas DELANOUE - "Optimal Control Via Occupation Measures and Interval Analysis"

    Résumé :

    In this lecture, we present a method based on occupation measures to compute a guaranteed lower bound to an optimal control  problem. Following Vinter approach, the optimal control problem is formulate into a linear programming problem of infinite dimension (measure Theory). Thank to Interval arithmetic, this linear programming problem can be approximate, in a reliable way. Finally, its solution gives a lower bound to the optimal cost. Examples will illustrate the principle of the methodology.

    Nicolas DELANOUE est membre du LARIS, Equipe SDO, et maître de conférence de 61è section CNU à l'Institut Universitaire Technologique d'Angers. Il développe des recherches à l'interface entre la robotique et l'analyse numérique.

     


    Vinicius Mariano GONÇALVES - "The tropical regulation problem"

    Résumé :

    In this talk the tropical (max-plus) regulation problem will be presented. This is the mathematical formulation of the problem of guaranteeing some time specifications in Timed Event Graphs. The recent developments in this setting will be given, making the connection with the also recently-developed tropical spectral theory. Aiming for future developments, the theoretical and practical challenges that remain to be surpassed will also be shown.

    Vinicius Mariano Gonçalves defended his Phd in November 2014 in UFMG Belo Horizonte (advisors Pr C.A. Maia and Pr L. Hardouin). He spent a research period  in Angers between september 2013 and july 2014. He is currently in postdoctoral position in University of Montpellier.
