abstract = {About $85\%$ of the primary energy is currently obtained
from fossil sources. In the next future, nuclear fusion can
significantly contribute to energy production: the fuel is
in principle unlimited and radioactive waste are short
lived. Next steps in fusion research are represented by the
two tokamaks ITER, which is under construction, and DEMO,
which is in its conceptual design phase. In this paper we
focus on a specific aspect of DEMO design, that is indeed
crucial for tokamak safe operation: plasma vertical and
shape control. It is well known that a plasma with elongated
cross-section exhibits a vertical instability that needs to
be feedback controlled. Typically on operating tokamaks, and
in ITER, this task is accomplished using in-vessel actuator
coils. Since in the present DEMO design these coils are not
foreseen, hereafter we assumed that all the actuator coils,
located outside the vessel, are used at the same time to
guarantee both vertical stabilization and shape control,
resorting to a suitable geometric decoupling. The
performance of the controller is shown in simulation using a
nonlinear evolution code during a plasma H-L
back-transition.},
