abstract

  • In this paper control-oriented dynamical models of current, horizontal and vertical displacement for Runaway Electrons (RE) beam in the plateau phase are presented. The dynamical models were obtained through gray-box identification techniques on experimental data collected on post-disruptive RE beam shots in the Frascati Tokamak Upgrade (FTU). Based on the identified models, the design of simple robust controllers to improve RE beam mitigation strategies is proposed and simulations results are provided.
