MPC strategies for density profile control with pellet fueling in nuclear fusion tokamaks under uncertainty
Christopher A. Orrico, Hari Prasad Varadarajan, Matthijs van Berkel +4
Control of the density profile based on pellet fueling for the ITER nuclear fusion tokamak involves a multi-rate nonlinear system with safety-critical constraints, input delays, an…
Nuclear fusion plasma fuelling with ice pellets using a neuromorphic controller
L. L. T. C. Jansen, E. Petri, M. van Berkel +1
In reactor-grade tokamaks, pellet injection is the best candidate for core plasma fuelling. However, density control schemes that can handle the hybrid nature of this type of fuell…
First demonstration of Super-X divertor exhaust control for transient heat load management in compact fusion reactors
B. Kool, K. Verhaegh, G. L. Derks +14
Nuclear fusion could offer clean, abundant energy. However, managing the immense power exhausted from the core fusion plasma towards the divertor remains a major challenge. This is…
Mixed-Integer MPC Strategies for Fueling and Density Control in Fusion Tokamaks
Christopher A. Orrico, Matthijs van Berkel, Thomas O. S. J. Bosman +2
Model predictive control (MPC) is promising for fueling and core density feedback control in nuclear fusion tokamaks, where the primary actuators, frozen hydrogen fuel pellets fire…
