Modélisation et identification de comportements de l'avion en vol turbulent par modèles à retards

Abstract : This study relates to the mathematical representation of the behaviour of the aircraft in atmospheric turbulence as well as the identification of the dynamics induced by the gust. The approach falls under a prospect for identification from tests carried out in the Flight Analysis Laboratory of the DCSD of ONERA in Lille. To achieve this, the plane is considered into various
elements which consist in the fuselage, the wing and the tail. The obtained model incorporates unsteady effects, modelled via Küssner functions, and clearly clarified delays.
Results in simulation confronting our model with recent work on modelling (Jauberthie's PhD thesis) highlight the fact that these phenomena have to be taken into account in the modelling. The comparison with experimental data shows that the tendencies observed during the tests are confirmed for our model.
The algebraic identification method initiated by Fliess and Sira-Ramirez in 2003 was extended to time delay systems. This technique based on the distributional framework allows to identify some delays and parameters of our model.
