I. INTRODUCTION 1,2 ITER willbe the most complex and powerful tokamak device ever built in the field of research on nuclear fusion by magnetic confinement, with a typical flattop current of about 15 MA. Its main heating power will be supplied byαgenerated by fusion particles reactions but, in order to reach this condition, 73 MW of 3 additional power from different sources will be needed. Even if the ITER design has attained a certain degree of maturity, many technical risks still remain, part of them having recently come to light thanks to physics results 4 from existing machines. Therefore, due to the large amount of power involved and to the consequent danger of damaging the machine, several operational constraints will have to be taken into account and a key role will be played by the active plasma control with which to reach the target performance. 5 The ITER plant control system (PCS) will basically have three purposes: a) to ensure reliable ITER operation; b) to fully explore the ITER operational space for physics experiments using advanced control techniques that employ a number of actuators comparable to presentday machines to control an increased number of parameters; c) to guarantee machine protection in conjunction with the ITER central interlock system (CIS). The main PCS physics and operation requirements are: plasma equilibrium control; plasma kinetic control; advanced operation control (profile control); active control of magnetohydrodynamic (MHD) instabilities; disruption avoidance and mitigation; event handling. The PCS will interface to CIS and to the general CODAC (Communication, Data Acquisition and Control) infrastructure and its network, with an estimated number of signals equal to about 5000 (data rates of about 30 MByte/s). While the supervisory control system will transmit the reference waveforms and the initial set of algorithms and parameters to the PCS, when a discharge 819
