Beschreibung:
The problem of confining a plasma, with sufficiently high density and temperature, is of crucial importance if nuclear fusion is to be made usable as a form of power generation. Tokamaks - devices with a toroidal geometry - are among the most popular candidates by which such confinement can be achieved. A tokamak separates a plasma from its surroundings by means of a magnetic field generated by several coils distributed around the plasma.
"The main topic of this monograph is the design of a feedback control system for magnetic fields to guarantee the plasma equilibrium inside a tokamak with a prescribed position and shape. Modelling and control details are presented, allowing the non-expert to understand the control problem. Starting from equations of magneto-hydro-dynamics, all the steps needed for the derivation of plasma state-space models are enumerated. The basics of electromagnetics are frequently recalled. The control problem is then described beginning with control of current and position - vertical and radial - and progressing to more challenging shape control. The solutions proposed vary from simple PIDS to more sophisticated MIMO controllers.
