Abstract

Global warming requires fast developments and deployments of electrified vehicles to reduce the ecological footprint of transportation. Waiting for both battery and fuel cell electric vehicles to fully mature, intermediate solutions to electrify the internal combustion engine-powered vehicles, such as Hybrid Electric Vehicles (HEV), have been developed during the last decades. This synthesis report is devoted to the structuration of real-time control algorithms for HEV using a systemic approach. It consists of an overview of my research activities during the last fifteen years at the L2EP (Laboratory of Electrical Engineering and Power Electronics of Lille) of the University of Lille. These activities deals with the organization at both local and global control of HEV independently of powertrain topologies and energy storage systems. To make easier the understandability of the dynamic interaction of complex systems, the Energetic Macroscopic Representation (EMR) formalism has been utilized along all my research activities in both top-down and bottom-up approach. Most of my activities have furthermore contributed to the French collaborative network MEGEVH, which aims to foster collaborations between academic institutions and industrial partners on energy modelling and energy management for electrified vehicles. In this way, the first chapter introduces the context of the research activities. Subsequently, the second chapter discusses on the stability problematics of the inversion-based control deduced from EMR. The third chapter deals with two different decomposition approaches of real-time global control of HEV while the fourth chapter details experimental validations using EMR for HEV. Perspectives for the coming years are drawn at the end of the report.
