Flight-Simulators for the ASDEX Upgrade Tokamak: Development of a New Software-In-the-Loop Tool and Controller Design for Advanced Divertor Configurations — •Marco Biasizzo1,2, Pierre David1, Matthias Gehring1, Renat Kermenov1, Mariano Ruiz2, Bernhard Sieglin1, Wolfgang Treutterer1, Hartmut Zohm1, and the ASDEX Upgrade Team1 — 1Max Planck Institute for Plasma Physics, 85748 Garching, Germany — 2Grupo de Investigación en Instrumentación y Acustica Aplicada, Universidad Politécnica de Madrid, 28031 Madrid, Spain
Flight-simulators (FS) for tokamaks ingest a discharge program and return the time evolution of plant and plasma variables, enabling rapid testing of scenarios and control algorithms. The current ASDEX Upgrade (AUG) FS, Fenix, uses a physics-based model for the plasma and a Simulink model of the tokamak control system. An alternative software-in-the-loop (SIL) version is under development; it runs an exact replica of the control system, removing modelling limits and reducing execution time. Synchronization and communication between the control system and the plasma and plant models are presented.
The SIL simulator will be used to implement and test a novel controller to regulate desired advanced divertor configurations (ADCs) and key plasma shape geometric descriptors. Model-based controller synthesis has begun with ADCs data obtained from the current FS. Fenix results were benchmarked against recent AUG experiments, showing quantitative agreement. This integrated approach promises faster, reliable controller development while saving experimental time.
