Adaptive control design and energy distribution estimation via nonlinear observer for runaway electron in FTU.

Popis výsledku v původním jazyce

The stabilization of post-disruptive runaway (RE) beams is of crucial importance to avoid major damages to the plasma facing components. RE beam dynamics are quite different from standard plasmas and deserve specific controllers to improve their confinement [1, 2, 3]. Mitigation techniques (MGI, shattered pellet injections) can be combined with RE beam stabilization andncontrolled current ramp-down strategies to provide a complete mitigation system. In this work we introduce an ad-hoc adaptive control technique, based on recent methodologies [11, 4, 5], tailored to improve the control scheme robustness necessary for machine portability. During the controlled RE beam ramp-down, data related to beam interaction with pellet/impurity injections have been collected as well as information related to expelled runaways hitting the Cherenkov probes [6] and RE beam instabilities.n
