Parametric Optimization for Tokamak Plasma Control System
Alexander Ovsyannikov, Noboru Sakamoto, Sergey Zavadsky
The problems of synthesis and design of feedback controllers in tokamaks are considered.
In order to design the control system for plasma current, shape and position the structural parametric optimization of transient processes is suggested. Optimization approach to plasma dynamic is based on the consideration of trajectory ensemble. This ensemble describes transient process in tokamak subject to the initial data and external disturbances. In the framework of this approach the optimization of dynamics of the trajectory ensemble in ITER tokamak is given. The trajectories of this ensemble are perturbed at the initial point set and the set of external disturbances.
