Modelling and Control of a Complex Multi-physic System Application to Helicopter flight axis control
TypeCommunications avec actes
A helicopter flight axis control, which is a complex multi-physic system, is modelled using an energetic based graphical tool. Element of the system are mainly composed of passive technologies and their number tends to increase years after years to improve the pilots comfort by adding new functions. Thanks to the recent march in electronic fields and in order to simplify flight structures, new active systems have come out in aeronautical systems, a specific sector which requires extreme rigors and approved technology. In this paper, a simplified helicopter flight axis control is modelled with the intention of controlling the helicopter stick force feedback. Using the Energetic Macroscopic Representation the detailed methodology presented in this paper is helpful to determine an adequate control for active systems with sampled signals.

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. ...
