Controllability and Optimal control at Low Reynolds number

Participants : Piernicola Bettiol [Université de Bretagne Occidentale (Brest)] , Bernard Bonnard, Laetitia Giraldi, Pierre Martinon [project-team COMMANDS] , Jean-Baptiste Pomet, Jérémy Rouot.

This new aera is somehow connected to the recent recruitment of L. Giraldi (CR2) in the Mc Tao team. The problem under study is to design strokes for swimmers at low Reynolds numbers, e .g. the Copepod swimmer (an abundant variety od zooplankton) or the Purcell swimmer. The problem was studied from the point of view of geometric optimal control [17] , [18] combining theoretical and numerical computations or controllability techniques [19] .
