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 aprescribed 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. Wherever possible, the various topics are rounded out with results obtained through the authors’ contributions to experiments with actual tokamaks. Mathematical details which are outside the normal province of control engineers are presented in an appendix for the interested reader. Gives the reader a comprehensive and up-to-date treatment of control in tokamak-generated magnetic fields Co-ordinated and self-contained presentation will save the reader time in literature searches and tying together scattered results from disparate research papers on tokamak control Commissioning of new tokamak reactors in the near future will make this book of significant importance INDICE: Introduction.- Part I: Plasma Modelling.- Plasma Modelling for Magnetic Control.- The Plasma Boundary and Its Identification.- Part II: Plasma Control.- Plasma Magnetic Control Problem.- Plasma Position and Current Controlat FTU.- Plasma Vertical Stabilization.- Plasma Shape Control at ITER.- Plasma Shape Control at TCV.- Plasma Shape Control at JET.- Appendices: Some Mathematical Background; Units Used in Plasma Physics.
