Boundary Layer Control

The Journal of the Royal Aeronautical Society, 1955
It has almost become a tradition in recent years to begin a paper on boundary layer by paying a tribute to the great Prandtl and his famous paper in which he introduced the conception of boundary layer into Fluid Dynamics.The year 1954 is, however, not only memorable to mark the passing of fifty years since Prandtl's classical demonstration of the ...

Approximate Controllability of Boundary Control Systems with Nonlinear Boundary Conditions

Applied Mechanics and Materials, 2014
The paper deals with the approximate controllability of a class of nonlinear delayed control systems in which the control is acted through the boundary of the region and the boundary conditions are nonlinear. The approximate controllability result is established provided the approximate controllability of the corresponding linear systems.

Funnel Control for the Boundary Controlled Heat Equation

SIAM Journal on Control and Optimization, 2015
Summary: We consider an output regulation problem for a single input single output system with dynamics described by the heat equation on some bounded domain \(\Omega\subset\mathbb R^d\) with sufficiently smooth boundary. The input is formed by Neumann boundary control, and the output is the surface integral of the state at the boundary.

Boundary Element Method for Boundary Control Problems

2007 Chinese Control Conference, 2006
In this paper, we discuss the numerical simulation for a class of convex boundary control problems. The boundary element method is used for the approximations of the problems. The a priori error estimates and a posteriori error estimators for the boundary element schemes are presented.

Boundary layer control

2003
Abstract Prandtl’s (1961B) historical lecture on the concept of boundary layer was given in the same year as the concept of its control was initiated. He started his renowned flow visualization tests and filming of a circular cylinder with a slot on one side where suction was applied.

Stabilization of Boundary Control Systems

1979
Let Ω be an open subset of Rn with the boundary Γ =∂Ω. A typical boundary control system can be described by an equation of the form $$ \begin{array}{*{20}{c}} {\frac{{\partial z}}{{\partial t}}\left( {t,x} \right) = Lz\left( {t,x} \right) + Bu\left( {t,x} \right),\quad t > O,\;x \in \Omega } \\ {z\left( {O,x} \right) = {z_O}\left( x \right),\quad x

Controllability Properties of Pseudo-Parabolic Boundary Control Problems

SIAM Journal on Control and Optimization, 1980
We study the boundary control of a pseudo-parabolic equation and compare the results to those of parabolic equations. We find that the pseudo-parabolic equation on a finite interval is controllable by means of boundary controls, but on a semi-infinite interval it is not controllable.
