In this lecture, the problems of position, current, and shape control of plasma in tokamak-type (toroidal) devices will be introduced. Modelling issues will be briefly discussed, and then the control problem will be described, beginning with the control of current and position and progressing to the more challenging shape control. The solutions proposed vary from simple PIDs to more sophisticated MIMO controllers. Eventually, the controller implemented at JET, the eXtreme Shape Controller, will be presented, along with a system, called Current Limit Avoidance, which has been implemented to address the problem of current saturations.
