Transient PDE-constrained optimal control problem is considered. Corresponding projection gradient method for its numerical solution leads to a set of convection-diffusion problems with different right-hand sides. Because of the small diffusion coefficient standard methods result in unstable numerical solutions, therefore advanced schemes for convection-diffusion equations are considered.
