Beschreibung
Stabilization of Navier–Stokes Flows presents recent notable progress in the mathematical theory of stabilization of Newtonian fluid flows. Finite-dimensional feedback controllers are used to stabilize exponentially the equilibrium solutions of Navier–Stokes equations, reducing or eliminating turbulence. Stochastic stabilization and robustness of stabilizable feedback are also discussed. The text treats the questions:
• What is the structure of the stabilizing feedback controller?
• How can it be designed using a minimal set of eigenfunctions of the Stokes–Oseen operator?
The analysis developed here provides a rigorous pattern for the design of efficient stabilizable feedback controllers to meet the needs of practical problems and the conceptual controllers actually detailed will render the reader’s task of application easier still. Stabilization of Navier–Stokes Flows avoids the tedious and technical details often present in mathematical treatments of control and Navier–Stokes equations and will appeal to a sizeable audience of researchers and graduate students interested in the mathematics of flow and turbulence control and in Navier-Stokes equations in particular. The chief points of linear functional analysis, linear algebra, probability theory and general variational theory of elliptic, parabolic and Navier–Stokes equations are reviewed in an introductory chapter and at the end of chapters 3 and 4.

Provides applied mathematicians with methods for control of fluids as examples of more general partial-differential-equation-control problems Gives the control researcher a more sophisticated method of treating flow-control problems than traditional passivity-based approaches Provides conceptual designs for controllers to start readers on the path to their own practical flow control systems Includes supplementary material: sn.pub/extras

From the book reviews:
“The book is well written and nice to read. Each chapter is followed by numerous references. Many of the results presented in the book come from papers by the author and co-authors. This book is an excellent introduction to the subject and is recommended to researchers wanting to learn about stabilization problems for parabolic equations.” (Jean-Pierre Raymond, Mathematical Reviews, March, 2015)()
