The nuclear industry has some of the most extreme environments in world, with radiation levels and extremely harsh conditions restraining human access to many facilities. One method for enabling minimal exposure hazards under these is through use gloveboxes that are sealed volumes controlled performing handling. While allow operators perform complex handling tasks, they put at considerable risk from breaking confinement and, historically, serious examples including punctured gloves leading...
The problem of avoiding saturation the coil currents is critical in large tokamaks with superconducting coils like ITER. Indeed, if current limits are reached, a loss control plasma may lead to major disruption. Therefore, Current Limit Avoidance (CLA) system essential operate safely. This paper provides first experimental evidence that online solution constrained quadratic optimization can offer valid methodology implement CLA. Experiments carried out on Tokamak \`a Configuration Variable...
Abstract The problem of avoiding saturation the coil currents is critical in large tokamaks with superconducting coils like ITER. Indeed, if current limits are reached, a loss control plasma may lead to major disruption. Therefore, Current Limit Avoidance~(CLA) system essential operate safely.

The plasma control system (PCS) for the first nonactive ITER operation phase will require simultaneous active monitoring and of many continuous discrete quantities. Considering unique challenges face, all controllers be integrated deployed with very little experimental time dedicated to PCS tuning development. In order maximize efficiency design, a formal engineering approach has been adopted. simplified way, design process starts definition requirements. Functionalities are then designed...
For robotic systems involved in challenging environments, it is crucial to be able identify faults as early possible. In not always possible explore all of the fault space, thus anomalous data can act a broader surrogate, where an anomaly may represent or predecessor fault. This paper proposes method for identifying from robot, whilst using minimal nominal training. A Monte Carlo ensemble sampled Variational AutoEncoder was utilised determine and through reconstructing live data. tested on...
