OPTIMAL CONTROLLER FOR STABILIZATION OF PLASMA VERTICAL POSITION IN AN ELONGATED TOKAMAK

A procedure is proposed to synthesize a feedback controller for the vertical position stabilization of the plasma in an elongated tokamak. The procedure is based on a computer aided design method allowing satisfactory compromises between power requirements and the dynamic behaviour of the overall control system; such an approach permits the takinginto account of the physical constraints on the feasibility of the power amplifiers.
