abstract = {<p style="text-align: justify;">In this paper we consider PDE-constrained optimization problems which incorporate
an $\mathcal{H}_1$ regularization control term. We focus on a time-dependent PDE, and
consider both distributed and boundary control. The problems we consider include
bound constraints on the state, and we use a Moreau-Yosida penalty function to handle
this. We propose Krylov solvers and Schur complement preconditioning strategies
for the different problems and illustrate their performance with numerical examples.</p>},
