Due to the consequences of global warming and significant emissions of greenhouse gases, several avenues of research have been conducted to either reduce these emissions or to propose solutions to eliminate the pollutants. One of the most promising avenues of research is the use of microalgae for the biofixation of CO2. These micro-organisms can sequester CO2 through photosynthesis. In order to obtain an optimal sequestration of CO2, the culture must be conducted in a favorable environment corresponding to optimal operating conditions.

This book presents advanced concepts in the field of Automatic Control to ensure the optimal functioning of the bioprocess. It describes the approach as a whole: modeling, identification, observers’ implementation and development of the control laws. Each step will be assessed through experimental assays.

About the authors/editors

Sihem Tebbani is Associate Professor in the Automatic Control department at SUPELEC in Gif-sur-Yvette, France. Her research interests include modeling, estimation, optimization and control of bioprocesses, and more particularly of microalgae and bacteria cultures.

Filipa Lopes is Associate Professor at LGPM, Ecole Centrale Paris, France. Her research interests are in the field of biological engineering with a focus on biofilms (biofouling, disinfection, dispersion, modeling) and bioprocess development (bacteria, microalgae) for wastewater treatment, high-value products and bio-energy production.

Rayen Filali has a PhD in Automatic Control obtained at SUPELEC in Gif-sur-Yvette, France. His PhD thesis, in the framework of a collaboration between SUPELEC and Ecole Centrale Paris, deals with the estimation and the robust control laws of microalgae cultures for the optimization of CO2 biological consumption.

Didier Dumur is Professor in the Automatic Control department at SUPELEC in Gif-sur-Yvette, France. His research interests cover theoretical and methodological aspects related to predictive control strategies and their application in multiple domains (robotics, bioprocesses, temperature control of buildings, etc.).

Dominique Pareau is Professor at LGPM and Director of the White Biotechnologies Chair of the Ecole Centrale Paris, France. Her research concerns chemical engineering and biotechnologies, from the understanding of microscopic phenomena to process design, by coupling modeling and experimentation, with applications in the fields of agroresources, microalgae, waste and effluent treatments, etc.
