AB - <p style="text-align: justify;">In this paper, we investigate a streamline diffusion finite element approximation scheme for the constrained optimal control problem governed by linear convection dominated diffusion equations. We prove the existence and uniqueness of the
discretized scheme. Then a priori and a posteriori error estimates are derived for the
state, the co-state and the control. Three numerical examples are presented to illustrate
our theoretical results.</p>
