High-Performance Object-Oriented Scientific Programming in Fortran 90
We illustrate how Fortran 90 supports object-oriented concepts by example of plasma particle computations on the IBM SP. Our experience shows that Fortran 90 and object-oriented m...

An automatic identifier of Confinement Regimes at JET combining Fuzzy Logic and Classification Trees
In modern thermonuclear fusion devices it is possible to distinguish distinct types of plasma confinement regimes which have different performance in terms of confinement time. Dis...

Plasma vertical stabilization with actuation constraints in the DIII-D tokamak
In the advanced tokamak (AT) operating mode of the DIII-D tokamak, an integrated multivariable controller takes into account highly coupled influences of plasma equilibrium shape,...

Control of ramp-up current profile dynamics in tokamak plasmas via the minimal-surface theory
The central task of current profile control during the ramp-up phase of a tokamak discharge is to find the actuator trajectories that are necessary to achieve certain desired curre...

Controllability analysis for current profile control in tokamaks
Abstract-- The control of the toroidal current density spatial profile in tokamak plasmas will be absolutely critical in future commercial-grade reactors to enable high fusion gain...
