On the Observer Design with Application to Battery State of Charge Estimation

A masterclass with Professor Mohamed Darouach, Université de Lorraine and UWA Robert and Maude Gledden Visiting Fellow.

Depletion of fossil fuels and worldwide awareness of environmental issues have resulted in an increased deployment of renewable energy sources. Energy storage utilising batteries is a core element in the transition into a clean energy future. This seminar concerns the design of observers also called software sensors to estimate system states, and its application to estimate the State of Charge (SoC) of batteries. The SoC of a battery, which is used to describe its remaining capacity, is a very important parameter and the estimation of SoC is a fundamental challenge for battery use. Accurate estimation of the SoC remains very complex and is difficult to implement, because battery models are limited and there are parametric uncertainties.In this presentation first the problem of the observer design is presented. After the formulation of the observer design, we address the analysis of the structure of the system and then present the concepts of observability, controllability and stability. Different approach for the observer design will be developed. The case of uncertain systems will be also be considered and its state estimation solution will be given by using an optimisation technic. Finally, in this presentation we will show how these methods can be applied to the estimation of the state of charge (SoC) of a Lithium-Ion Battery.

Mohamed Darouach graduated from the Engineering school Ecole Mohammadia d’Ingénieurs, Rabat, Morocco, in 1978, and received the Doctor Engineer and Doctor of Sciences degrees from Nancy University, France, in 1983 and 1986, respectively. From 1978 to 1986 he was Associate Professor and Professor of automatic control at the Engineering School Ecole Hassania des Travaux Publics, Casablanca, Morocco. Since 1987 he has been a Professor at Université de Lorraine, France. He is a distinguished Professor “Professor of Exceptional Class 2” (the highest existing position in France). He has been a Vice Director of the Research Centre in Automatic Control of Nancy (CRAN UMR 7039, Nancy-University, CNRS) from 2005 to 2013. He obtained a degree Honoris Causa from the Technical University of IASI and since 2010 he has been a member of the Scientific Council of Luxembourg University. From 2013 to 2018 he was a Vice Director of the University Institute of Technology of Longwy (IUT, Université de Lorraine). Since July 2018 he has been the adviser of the Director of the IUT of Longwy, France. He has published more than 150 journal papers (including more than 30 in IEEE-TAC and more than 20 in Automatica). He held invited positions at University of Alberta, Edmonton and The University of Western Australia. Professor Darouach is a Robert and Maude Gledden Senior Visiting Fellow, administered by the Institute of Advanced Studies at UWA, and also a Forrest Visiting Fellow. His research interests are in the control theory, observers design, and control of large-scale scale systems with applications.
