Felici, F.Sauter, O.2012-03-222012-03-222012-03-22201210.1088/0741-3335/54/2/025002https://infoscience.epfl.ch/handle/20.500.14299/78937WOS:000300624400002A computational method is presented to determine the tokamak actuator time evolution (trajectories) required to optimally reach a given point in the tokamak operating space while satisfying a set of constraints. Usually, trajectories of plasma auxiliary heating, current drive and plasma current required during the transient phases of a tokamak shot to reach a desired shape of the plasma temperature and safety factor (q) profiles are determined by trial-and-error by physics operators. In this paper, these trajectories are calculated by solving a non-linear, constrained, finite-time optimal control problem.Internal Transport BarriersCurrent DriveTcv TokamakDiii-DElectronConfinementEquilibriaDischargesProgressSystemstext::journal::journal article::research article
