Exploration of candidate fusion reactor regimes by real time control of tokamak plasma shape

Himank Anand

The potential of nuclear fusion to provide a practically inexhaustible source of energy has motivated scientists to work towards developing nuclear fusion tokamak power plants. Stable operation of a tokamak at high performance requires simultaneous treatme ...

Real-time control of ELM and sawtooth frequencies: similarities and differences

Jonathan Graves

ELMs and Sawteeth, located in different parts of the plasma, are similar from a control engineering point of view. Both manifest themselves through quiescent periods interrupted by periodic collapses. For both, large collapses, following long quiescent per ...

Hierarchical Model Predictive Control in Fusion Reactors

Stefano Coda, Jean-Marc Moret, Hoang Bao Le

Nuclear fusion still has to pass several milestones on its way to successful energy production, one of them being successful plasma stabilization. The present article presents an innovative control implementation related to plasma control for the generatio ...

Physics of the conceptual design of the ITER plasma control system

Jonathan Bryan Lister, Richard Pitts

The ITER plasma control system (PCS) will play a central role in enabling the experimental program to attempt to sustain DT plasmas with Q = 10 for several hundred seconds and also support research toward the development of steady-state operation in ITER. ...
