Consider a rigid body immersed in an infinitely extended Navier–Stokes fluid. We are interested in self-propelled motions of in the steady state regime of the system rigid body-fluid, assuming that the mechanism used by the body to reach such a motion is modeled through a distribution of velocities on . If the velocity V of is given, can we find that generates V? We show that this can be solved as a control problem in which is a six-dimensional control such that either , an arbitrary nonempty open subset of ∂Ω, or . We also show that one of the self-propelled conditions implies a better summability of the fluid velocity.
