Add to ORKGAbstract. In this paper, we investigate the error estimates of a qua-dratic elliptic control problem with pointwise control constraints. The state and the co-state variables are approximated by the order k = 1 Raviart-Thomas mixed finite element and the control variable is dis-cretized by piecewise linear but discontinuous functions. Approximations of order h 3 2 in the L2-norm and order h in the L∞-norm for the control variable are proved. 1
