Model-based control of the magnetic flux profile in a Tokamak plasma

Abstract

A new model-based controller for the magnetic flux profile in a Tokamak plasma was developed using a simplified model of the magnetic flux dynamics. This simplified model is based on physically relevant dynamics that take into account the distributed nature of the system. Shape constraints on the controlled inputs are introduced, representing the limitations on the shape of the current profiles deposed by non-inductive current sources on the plasma. Some simulation results are presented and discussed.
