abstract = {<p style="text-align: justify;">The convergence of $H$<sup>1</sup>-Galerkin mixed finite element methods for elliptic
optimal control problems is studied and postprocessing operators are used to establish
the superconvergence for control, state and adjoint state variables. A numerical example
confirms the validity of theoretical results.</p>},
