摘要：
In this paper, we study an optimal control problem for the 2D MHD equations with memory in bounded domains with Dirichlet boundary conditions, where the time needed to reach the desired state plays an essential role. We first prove the existence of optimal solutions. Then we establish the first-order necessary and second-order sufficient optimality conditions. The second-order optimality ones obtained in the paper seem to be optimal in the sense that the gap between them is minimal.
