Présentation
I'm PhD student at the UMR MISTEA at INRAE (Montpellier, France) and the Valse team at Inria (Lille, France) with an INRAE/Inria scholarship. I started the Ph.D. program on September 1st, 2022. I received my Licence degree from the Mathematics Department at the Université d'Abomey-Calavi (Benin). I obtained an M. Sc. degree in Pure Mathematics at the Institut de Mathématiques et de Sciences Physiques (Benin) and an M. Sc. degree in Mathematics and Modeling at the Sorbonne Université (Paris). My works aims to develop control methods to pilot a original system of three interconnected bioreactors to reuse wastewater in agriculture. More particularly, it is a problem called "setpoint tracking", such "setpoint" being the result of the resolution of an optimal control problem solved using crop irrigation model. However, optimal solutions should be expressed as feedback that depend on the nitrogen in the soil, which a priori is not available and another difficulty is related to the various uncertainties in the model parameters. We would propose brings concrete answers to these challenges by designing the so-called "adaptive observer" for the joint estimation of nitrogen and uncertain parameters.
A. Rapaport, D. Efimov, R. Ushirobira and J. Harmand are my advisors and I'm grateful to INRAE and INRIA Institutes for the PhD grant.
