Abstract :
The concept of comprehensive, integrated control of a tokamak reactor using modern optimal control theory is presented. The plasma models of electromagnetic and kinetic dynamics and constraints are defined and transformed into a form consistent with linear optimal control theory. Additionally, a model of RF heating and current drive developed for this control effort is shown. The feedback gains derived from the linear control model are tested and analyzed in the Tokamak Simulation Code. Preliminary electromagnetic control results are presented. Preliminary results obtained by combining the poloidal flux-diffusion (distributed parameter) and the circuit model of the active PF (poloidal field) coils and structural eddy currents (lumped parameters) are encouraging
