EMR: Multi-physical Formalism for Control of Energetic Systems

Macroscopic Energy Representation (MER) is a graphical formalism for representing energy systems. It was developed in the 2000s by Lille's Laboratoire d'Électrotechnique et d'Électronique de Puissance (L2EP) :

• representation, because REM allows you to define a synthetic, graphical organization of mathematical modeling for complex systems;

• energy, because REM highlights the interactions and energy exchanges between the elements that make up a multiphysical system;

• macroscopic, as REM allows you to describe a system without having to read too much into it graphically.

The REM approach is fundamentally based on a systemic approach, in the sense that the subsystems of a system are studied, not separately but together, in a relationship of reciprocal dependence (interaction).

"Everything that happens (or begins to happen) presupposes something to which it succeeds, according to a rule". This quote from Immanuel Kant sums up the principle of causality, one of the founding principles of REM. REM is based on this principle, in other words, on integral causality, which underpins the notion of energy. The exclusive use of integral causality in REM enables the systematic deduction of a control structure. A methodology has thus been put in place to facilitate the development of control for new, increasingly complex and multiphysical systems. REM is thus an aid to guide the engineer in the physical organization of his modeling in order to obtain the control.

Various universities teach this new approach , both in France (Université Lille 1, Arts & Métiers Paris Tech centre Lille, Polytech Lille, Université de Franche-Comté, Université de Paris VI) and internationally (Université de Québec Trois Rivières).
