Tracking control for an ellipsoidal submarine driven by Kirchhoff's laws
Résumé
In this paper, we study the control of an ellipsoid immersed in an infinite volume of ideal fluid. The dynamics of the uncontrolled body are given by Kirchhoff's laws. By adopting a backstepping viewpoint, we prove that the position and the attitude of the solid can be forced to approximatively follow any given path, using three controls (two controls for the direction and one control for the velocity). Moreover, we prove that the controlled mechanical system (which includes the momenta) is completely controllable in arbitrary small time.
