Energetic Macroscopic Representation (EMR) is a graphical tool used to organize simulation models. EMR formalism is based on action reaction principle, which organizes the system model as interconnected subsystems according to the integral causality. An inversion of this description leads to macro-control blocks.

EMR formalism has been introduced for research and development in complex electromechanical drives by Professor Alain Bouscayrol.

Additional information about the EMR methodology and its applications can be found at the EMR website hosted by the University of Lille.
