Energetic Macroscopic Representation (EMR) Workshop
14/05 09:30 – 16/05 17:00
At the Tallinn University of Technology, NRG building (NRG-422 ja NRG-223)
The workshop is aimed at doctoral students in engineering and technology. The workshop will be conducted in English.
This three-day workshop is focused on the Energetic Macroscopic Representation (EMR) methodology for modelling and controlling complex electromechanical systems.
EMR is a graphical formalism introduced in 2000 to describe complex electromechanical systems. It has since been extended to complex multi-physical systems (thermal science, electrochemistry, fluid mechanics, etc.). EMR is based on the action-reaction principle to organize the interconnection of models of subsystems according to the physical causality (i.e., integral causality). This description highlights the 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 graphical descriptions, such as Bond Graphs or Causal Ordering Graphs (COG), EMR has a more global energetic view and contributes to the system’s control design. It differs from structural description tools such as Physic Modelling Language (PML), which uses object-oriented modelling language, which makes its libraries coupled like physical units. EMR focuses on the system function and not only 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.

Professor Alain Bouscayrol
Professor Alain Bouscayrol is a full professor at the University of Lille, France, and his research focuses on the control of energy conversion systems, in particular the development of graphical descriptions such as the Energetic Macroscopic Representation (EMR). He has applied his research to a variety of electrified vehicles, from electric cars to hybrid trains, and has participated in hardware in-circuit testing.
Professor Betty Lemaire-Semail
Professor Betty Lemaire-Semail is a full professor at the University of Lille, France, and his research focuses on the modeling and control of electrical systems, including piezoelectric actuators used in precision positioning. Professor Lemaire-Semail's recent work, for example, deals with vibratory tactile signals resulting from lateral forces generated by a traveling wave.
