Présentation

- José RAGOT received the "Diplome d'Ingénieur" (Engineer's Degree) with specialization in control from the Ecole Centrale de Nantes (France) in 1969. Then, he joined the University of Nancy (France) where is received the "Diplôme d'Etudes Approfondies" (Masters' Degree) in 1970. In 1973 he obtained the "Diplôme de Doctorat" (Ph. D. degree), a position as assistant professor at University Henri Poincaré in Nancy, and in 1980 the "Diplôme de Doctorat-es-Science". José Ragot moved up to professor in 1985 at the Institut National Polytechnique de Lorraine (INPL, National Polytechnic Institute of Lorraine). Presently he is a Professor (with highest degree "Classe Exceptionnelle") at the Ecole Nationale Supérieure de Géologie (french "Grande Ecole"). - José RAGOT is researcher in the Centre de Recherche en Automatique de Nancy (CRAN, CNRS UMR 7039) where he was the head of the group diagnosis during 12 years. His major research fields include data validation and reconciliation, process diagnosis, fault detection and isolation, fault tolerant control. A second part of his activities is devoted to modelisation adapted to process diagnosis and mainly in the field of multi-models or polytopic models. - He has successfully advised 70 Ph.D and 3 H.D.R (French D. Sc.) and published about 500 refereed technical communications including 150 papers in international journals, 350 communications in international conferences, 4 books, 12 chapters in collective volumes. A list of these publications can be founded at [http://www.cran.univ-lorraine.fr/perso/jose.ragot/](http://perso.ensem.inpl-nancy.fr/Jose.Ragot/). Applications have been in various fields such as mineral and metallurgical processing, chemical engineering, water treatment, aerospace, environmental processes (air pollution, water purification, water distribution), nuclear powerplants. - Since 1980, José RAGOT was the conductor of about 60 industrial research projects (with EDF, ELF, ARCELOR MITAL, AIRLOR, PECHINEY, ALSTOM, SNECMA, TOTAL CIE MINIERE, SOLLAC, LAFARGE, DELPHI, RHÔNE-POULENC, PSA, AIRBUS, THALES, IRH, AIRLOR, ESIA, MDPA, PEC-RHIN …). He was a member of 300 Ph. D. committees (France, Spain, Algeria, Germany, Belgium, Russia, Tunisia) He regularly contributes to national and international activities as a member of TC6.4 and TC6.2 of IFAC, through conferences organisation, international program committee of conferences, reviewer in international journals and conferences, national expert for research project of the french CNRS, national expert for laboratory activities evaluation for the French Ministary of Research. He was invited at several universities as a lecturer : EPFL (Lauzane, Suiss), UTC (Compiègnes, France), ENIT (Tunis, Tunisie), ENIM (Monastir, Tunisie), Jijel University (Annaba, Algérie), ESISAR (Valence, France), …
