EMR'11 has attracted 45 attendees from 6 countries. They have benefited of the nice organization of LEI of EPFL. Scientists, Master and PhD students have appreciated simulation and practical works in order to better acquire EMR concepts. Moreover valuable discussions have been issued on future developpements and applications of EMR.


This workshop was focused on the Energetic Macroscopic Representation (EMR) methodology for modelling and control of complex energetic systems.

This Summer School was dedicated to Master and PhD students, Engineers and scientists, both from academy and industry, who 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.

EMR is a graphical modelling tool, which has been introduced in 2000 to describe complex electromechanical systems; and it has been extended to other energetic systems . 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 Graph (COG), EMR has a more global energetic view and contributes to system’s control design. Differing from non-causal modelling tools such as Physic Modelling Language (PML) using Object-Oriented Modelling Language (which makes its libraries to be coupled in the same way as physical units), EMR is focused on the system function but 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. University of Tsinghua and Harbin Institute of Technology (China), UNiversity Carlos III of Madrid (Spain) will teach EMR in the coming years. The first international EMR workshops were held in Lille (France) in 006. The previous EMR summer schools took place in Harbin (China, EMR'08) in 2008 and in Trois-Rivières (Canada, EMR'09). EMR'11, organized by Ecole Polyetechnique Fédérale de Lausanne, will be held on July 4-6 and is extended for PhD student by the EPFL's energy doctoral school on July 6-7.
