Multi-physic system simplification method applied to a helicopter flight axis active control
TypeCommunications avec actes
A helicopter flight axis control, which is a complex multi-physic system, is modelled using an energetic based graphical tool: the Energetic Macroscopic Representation. Elements of the system are mainly composed of passive technologies and their number tends to increase year after year to improve the pilots comfort by adding new functions. A new methodology is proposed to transform the system into a new active one by replacing some hydro-mechanical elements by a new controllable active mechanical source. The challenge is to simplify the flight control architecture while preserving the global behaviour of the system.

Modelling and Control of an Effort Feedback Actuator in Helicopter Flight Control Using Energetic Macroscopic Representation MARTIN, Mikael; GOMAND, Julien; MALBURET, François; BARRE, Pierre-Jean (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. ...
