abstract

Let be a velocity vector field of steady-state fluid flow in a bounded container. We do not suppose that is stable. For each fluid flow which is close to at time moment t = 0 we propose a mathematical construction of feedback control from the boundary of the container which stabilize to this flow, i.e. which forces this flow to tend to with prescribed exponential rate. We introduce a notion of “real process” which is an abstract analog of fluid flow or (in other version) of numerical solution of Navier-Stokes equations. Real process differs from exact solution of three-dimensional Navier-Stokes equaitons on some small fluctuatons. Alhtough construction of feedback control is based on precise solving of Navier-Stokes equations, feedback control obtained by this method can react on unpredictable fluctuations mentioned above damping them. Such construction can be useful for numerical calculation because there fluctuations appear always.
