A new model of heating, current drive, torque and other effects of neutral beam injection on
NSTX-U that uses neural networks has been developed. The model has been trained and …

A 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 …

In tokamak fusion plasmas, control of the spatial distribution profile of the toroidal plasma
current plays an important role in realizing certain advanced operating scenarios. These …

A controller is designed for the tokamak safety factor profile that takes real-time-varying

We consider the optimal tracking problem for a divergent‐type parabolic PDE system, which
can be used to model the spatial‐temporal evolution of the magnetic diffusion process in a …

Scenario development in tokamaks is an open area of investigation that can be approached
in a variety of different ways. Experimental trial and error has been the traditional method …

Stable, high-performance operation of a tokamak requires several plasma control problems
to be handled simultaneously. Moreover, the complex physics which governs the tokamak …

In order for ITER to be capable of operating in advanced tokamak operating regimes,
characterized by a high fusion gain, good plasma confinement, magnetohydrodynamic …

A new model for prediction of electron density and pressure profile shapes on NSTX and
