Automatic control

CRONE

The general subject of this thematics research is the (real or complex) non-integer derivative as operator and modeling tool, its synthesis extended to complex field and also its applications in the engineering sciences. More precisely, in reason of the affiliation of this thematics to the Automatic Control Group, which is constituted of 3 components, one particularly privileged research axis is in applying fractional derivative in automatic control, notably in system identification through non integer model, and in robust control through the CRONE control (Commande Robuste d’Ordre Non Entier, a French acronym for Robust Control of Non Integer Differentiation).

Scientific presentation

The motivations of such thematics are dictated by the constant concern to defend the following thesis: given its « compactness » properties, the non-integer differentiation operator forms the mathematical tool par excellence to model with a minimum of parameters the highest number of phenomena falling under as well engineering sciences as biological and physico-chemical sciences. To defend this thesis, the members of this thematics strive to obtain the maximum of determining theoretical results then, to show the applicative interest and their applicability, to realize them by technological transfers falling under a true valorization of upstream research. The thematics “Systems with non-integer derivatives » falls under as well system theory, automatic control as robotics.

On the  2015-2020 period, the research works are notably diffused at the international level through 4 books.

The partnership research is held through new collaborations as well at local levels (Valéol, Beyond The Sea, Air Marine) as national ones (Groupe PSA) or  international ones (Robert Bosch), and is notable enhanced by 25 patents. The multidisciplinary research is developed with new collaborations (Labri (1 thesis in progress), Gipsa-Lab (1 defended thesis)).

In matter of doctoral supervisory, the effort is maintained on the diversification of the financing of the PhD students: 8 Cifre, 3 contracts (national industrials), 3 allowances, 1 Region, 1 allowance ENS, 1 Cluster SysNum Idex, 1 AAP Multidisciplinary Univ. Bx, foreign partnerships: 3 with ENIG (Tunisia), 4 with Liban, 1 with Brazil.

Résumé en français

Le sujet général de cette thématique de recherche est la dérivée non entière (réelle ou complexe) en tant qu’opérateur et outil de modélisation, sa synthèse étendue au domaine complexe ainsi que ses applications dans les sciences de l’ingénieur. Plus précisément, en raison de l’appartenance de cette thématique au Groupe Automatique, qui est constitué de 3 composantes, un axe de recherche particulièrement privilégié est l’application de la dérivée fractionnaire en automatique, notamment en identification de systèmes par des modèles non entiers, et en commande robuste par la commande CRONE (Commande Robuste d’Ordre Non Entier).
