Exponential stabilization of the linearized Navier-Stokes equation by pointwise feedback noise controllers
نویسنده
چکیده
We address the problem of exponential stabilization in probability of the linearized Navier–Stokes equations in an equilibrium point. This is done by designing a linear stochastic feedback controller with support in a point or on a discrete set of points of the domain. This controller consists of steady-state impulse component with support in a finite set of points modulated by an unsteady feedback noise controller.

The Internal Stabilization by Noise of the Linearized Navier-stokes Equation
i=1 Vi(t)ψi(ξ)β̇i(t), ξ ∈ O, where {βi}i=1 are independent Brownian motions in a probability space and {ψi}i=1 is a system of functions on O with support in an arbitrary open subset O0 ⊂ O. The stochastic control input {Vi}i=1 is found in feedback form. One constructs also a tangential boundary noise controller which exponentially stabilizes in probability the equilibrium solution.

We study the exponential stabilization of the linearized Navier-Stokes equations around an unstable stationary solution, by means of a feedback boundary control, in dimension 2 or 3. The feedback law is determined by solving a Linear-Quadratic control problem. We do not assume that the normal component of the control is equal to zero. In that case the state equation, satisfied by the velocity f...

متن کاملInternal Exponential Stabilization to a Nonstationary Solution for 3D Navier-Stokes Equations
We consider the Navier–Stokes system in a bounded domain with a smooth boundary. Given a sufficiently regular time-dependent global solution, we construct a finite-dimensional feedback control that is supported by a given open set and stabilizes the linearized equation. The proof of this fact is based on a truncated observability inequality, the regularizing property for the linearized equation...
متن کاملStabilization of Navier-stokes Equations by Boundary Feedback
In this paper, we consider the stabilization of steady state solutions to Navier-Stokes equations by boundary feedback control. The feedback control is determined by solving a linear quadratic regulator problem associated with the linearized Navier-Stokes equations. The control is effected through suction and blowing at the boundary. We show that the linear feedback control provides global expo...
