Analysis of the SQP-method for optimal control problems governed by the instationary Navier-Stokes equations based on Lp-theory

Preprint-Reihe des Instituts für Mathematik, Technische Universität Berlin
The aim of this article is to present a convergence theory of the SQP-method applied to optimal control problems for the instationary Navier-Stokes equations. We will employ a second-order sufficient optimality condition, which requires that the second derivative of the Lagrangian is positive definit on a subspace of inactive constraints. Therefore, we have to use $L^p$-theory of optimal controls of the instationary Navier-Stokes equations rather than Hilbert space methods. We prove local convergence of the SQP-method. This behaviour is confirmed by numerical tests.
