Abstract: 
I will present some recent results on the analysis of two swimmer models (one actuated externally and the other internally). These models provide an example of propulsion at low Reynolds number resulting from the periodical beating of a passive elastic filament. Motions produced by generic periodic actuations are studied within the regime of small compliance of the filament. The analysis shows that variations in the velocity of beating can generate different swimming trajectories. Motion control through modulations of the actuation velocity will be discussed.
