In this talk we present a block-diagonal preconditioner for the discretized distributed optimal control problem of the Stokes equations. Using this in preconditioned Krylov subspace methods results in mesh-independent and robust (i.e.: parameter-independent) convergence rates. Numerical examples are given, which illustrate the theoretical results.
