Complementary use of BG and EMR formalisms for multiphysics systems analysis and control
Communication avec acte
In this paper, a complex multiphysics system is modeled using two different energy-based graphical techniques: Bond Graph and Energetic Macroscopic Representation. These formalisms can be used together to analyze, model and control a system. The BG is used to support physical, lumped-parameter modeling and analysis processes, and then EMR is used to facilitate definition of a control structure through inversion-based methodology. This complementarity between both of these tools is set out through a helicopter flight control subsystem.

Modelling and Control of an Effort Feedback Actuator in Helicopter Flight Control Using Energetic Macroscopic Representation Communication avec acteMARTIN, Mikael; BARRE, Pierre-Jean; GOMAND, Julien; MALBURET, François (IMAACA 2011, 5th International Conference on Integrated Modeling and Analysis in Applied Control and Automation, 2011)In helicopter field, electromechanical devices controllers are usually designed and tuned from global analysis with transfer functions calculations. This leads to control architectures with a reduced number of controllers. ...
