Energetic Macroscopic Representation


Walter LHOMME(lecturer) Associate professor at University of Lille 1.

Betty LEMAIRE-SEMAIL Professor at University of Lille 1.

Philippe BARRADE Associate professor at Ecole Polytechnique Fédérale de Lausanne.



Energetic Macroscopic Representation (EMR) has been introduced in 2000 for research development in complex electromechanical drives especially multi-drives systems. EMR is based on action reaction principle, which organizes the system as interconnected subsystems according to the integral causality. What's more, an inversion of this description leads to macro-control blocks.
This presentation will focus on the EMR methodology for modelling of complex electromechanical systems. The inversion-based control systematically deduced from EMR will be dealt with in the next presentation.


Intervention contents

This intervention will present the EMR rules. It will break down into four parts:

1. Why a macroscopic representation and energetic?
2. Basic elements of EMR
3. Association rules
4. EMR example of an electromechanical system
