EMR'13, " Modelling and control using EMR"
Application to hybrid electric vehicles and others”
Summer School (3 ECTS)
University Lille1 (France)
09-11 Septembre 2013
The first international EMR workshops was held in Lille (France) in June 2006. The previous EMR summer schools took place in Harbin (China, EMR'08) in September 2008, in Trois-Rivières (Canada, EMR'09) in September 2009, in Lausanne (Switzerland, EMR'11) in July 2011, and in Madrid (Spain, EMR’12) in June 2012. After 7 years, the international EMR summer school has come back in Lille for September 2013.
EMR'13 has been successfully organized by University Lille1 / L2EP. There were 54 attendees from 7 countries (Argentina, Canada, France, Italy, Portugal, Romania and Switzerland); about 2/3 of attendees were Master or PhD Students, 3 lectures on concepts, 16 lectures on applications, 2 simulations sessions (Electric Vehicle, Wind turbine, Photovoltaic System), 1 practical session plus the PhD works. 3 ECTS have been delivered by University Lille1 to foreign Master and PhD students.

This workshop was focused on the Energetic Macroscopic Representation (EMR) methodology for modelling and control of complex electromechanical systems.
This Summer School was dedicated to Master and PhD students, Engineers and scientists, from both academia and industry, which have to model and control new electromechanical systems such as industrial multi-drive systems, traction and propulsion systems, hybrid electric vehicles, or renewable energy generation systems.
This year, the traditional summer school has been linked to the Doctoral School “Science for Engineers” of the Université Lille1. The opportunity has been given to the PhD students to follow this seminar (3 ECTS). They have benefited from the practical exercises that have been proposed. They had the possibility to use the EMR methodology on examples they have proposed, solved and presentd.
EMR is a graphical modelling tool that was introduced in 2000 at L2EP to describe complex elec-tromechanical systems. EMR has since been extended to complex multiphysics systems (combining thermal science, electrochemistry, fluid mechanics …). EMR is based on the action-reaction principle to organize the interconnection of sub-systems according to the physical causality (i.e. integral). This description highlights energetic properties of the system (energy accumulation, conversion and distribution). Moreover, an inversion-based control can be systematically deduced from EMR using specific inversion rules.
Compared with other causal modelling tools such as Bond Graphs or Causal Ordering Graphs (COG), EMR has a more global energetic view and contributes to system’s control design. It differs from non-causal modelling tools such as Physic Modelling Language (PML) using Object-Oriented Modelling Language, which makes its libraries to be cou-pled in the same way as physical units. EMR is focused on the system function and not only on the system structure. EMR gives insights into the real energy operation of systems and allows a deep understanding of its potentialities from a dynamic point of view.
In short, the distinct features of EMR lie in its clarity of physical concepts, as well as their physical causality, and its functional modelling rather than a structural modelling, hence contribute significantly to the design of the control and to energy management of systems.
EMR is taught in various universities in France since 2000, at University of Québec à Trois Rivières since 2002 and at EPF Lausanne (Switzerland) since 2005.
