COMPUTATIONAL OPTIMIZATION AND APPLICATIONS, cilt.57, sa.3, ss.703-729, 2014 (SCI-Expanded)
In this paper, we analyze the symmetric interior penalty Galerkin (SIPG) for distributed optimal control problems governed by unsteady convection diffusion equations with control constraint bounds. A priori error estimates are derived for the semi- and fully-discrete schemes by using piecewise linear functions. Numerical results are presented, which verify the theoretical results.
