Des Architectures de la Commande Distribuée pour des Grands Réfrigérateurs Cryogéniques

par Van vuong Trinh

Projet de thèse en Automatique - productique

Sous la direction de Mazen Alamir et de Patrick Bonnay.

Thèses en préparation à Grenoble Alpes , dans le cadre de Electronique, Electrotechnique, Automatique, Traitement du Signal (EEATS) , en partenariat avec Grenoble Images Parole Signal Automatique (laboratoire) et de Signal automatique pour la surveillance, le diagnostic et la biomécanique (equipe de recherche) depuis le 01-11-2014 .


  • Résumé

    Cryogenic refrigerators are processes that produce low temperature liquid helium for use in the cooling of superconductors in facilities such as particles accelerators (CERN) or fusion nuclear reactors (ITER, JT-60SA). The control of the underlying thermodynamic cycles is a major issue for several reasons: Energy saving, operability and security fulfilment and modularity. The PhD lies within a French ANR project (CryoGreen) which gathers the following partners: - CEA-INAC-SBT (Grenoble) - GIPSA-lab (Grenoble) - CERN (Geneva) This project follows several joint works between the partners that induced crucial advances in the deployment of modern control architecture (constrained MPC, nonlinear observers) as well as the development of a modular nonlinear models for the experimental cryogenic station available at CEA-INAC-SBT. The PhD addresses the problem of distributed control design in order to derive a modular and scalable control architecture. This is based on recent works by the partners that has to be consolidated, improved, extended and experimentally validated. Keywords: control theory (optimal control, predictive control, observer design), optimization and scientific programming, process control (thermodynamic).
