IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn this work, a data-driven model procedure aimed at identifying the dynamical behavior of the thermal distribution over the limiter surface placed in nuclear fusion plant facilities is provided. In particular, we focused on experimental data collected in the in Frascati Tokamak Upgrade (FTU) where a cooled liquid lithium limiter (CLL) with a capillary porous system (CPS) technology is adopted. Thus, a nonlinear dynamical system, namely a Hammerstein-Wiener model, has been investigated and opportunely identified in order to predict the thermal distribution over the CLL. The identified system is able to predict spatiotemporal thermal information even in the worst case scenario when disruptive events occur during plasma experiments.
