Partial Moments in System Identification

About Jean-Claude TrigeassouRégis OuvrardThierry Poinot

Régis Ouvrard did all his graduate studies at the University of Poitiers: M.S. degree in Electronics Electrical Engineering and Automation in 1992 Certificate of aptitude for secondary school teachers in Electronics in 1996 Ph.D. degree in Automatic Control in 1997 and Accreditation to supervise research in 2022. Since 1999 he has been an associate professor at the University Institute of Technology in Poitiers. His research topics are dedicated to system identification and data-driven modelling. He has contributed significantly to the dissemination of the tools based on partial moments in system identification. The common denominator in the application of the tools that Régis Ouvrard develops is the protection of the environment and biodiversity. For example he is currently proposing new population dynamics models to study the impacts of global changes on biodiversity. Thierry Poinot received his Ph.D. in 1996 from the University of Poitiers France in the field of automatic control. He has been a professor at the University of Poitiers since 1996. He is a member of the Computer Science and Automatic Control for Systems Laboratory at the University of Poitiers of which he has been the director since 2022. His research interests are in the areas of system identification and data-driven modelling including the identification of linear and nonlinear continuous-time systems the identification of linear parameter-varying systems and the modelling and identification of fractional systems. His current activities focus on modelling and identifying Li-ion batteries and modelling population dynamics applied to biodiversity. Jean-Claude Trigeassou received the Maîtrise EEA diploma from the University of Bordeaux in 1969 the French Agrégation of applied physics in 1971 the Ph.D. degree and the Doctorat dEtat in automatic control in 1981 and 1987. From 1988 to 2006 he has been a professor at ESIP in Poitiers University. Since his retirement he developed an original theory entitled Infinite State Representation of fractional order differential systems. His first thesis was dedicated to the method of moments with applications to identification and control. Then he defined and developed the reinitialized partial moment theory and its application to the identification of discrete and continuous-time systems. In parallel he has investigated output error identification methodology and particularly parameter estimation of continuous systems with application to the diagnosis of electrical machines.
