Abstract :
In this paper a typical optimal control problem arising in tokamak engineering is presented and solved. The attention is focused on the selection of the optimal number and positions of the Poloidal Field (PF) coils to keep in MHD equilibrium a tokamak plasma of given characteristics. The problem is casted as a sparse optimal least square problem and it is solved by using a QR factorizations with pivoting. A simple case study is applied to a tokamak configuration of the ITER-class type.
