Abstract

In this paper, the structure of an Electro Hydrostatic Actuator (EHA) devoted to flight control surfaces is firstly described by its Causal Bond Graph (CBG). Then, verifying the inversion conditions, the Bicausal Bond Graph (BBG) can be obtained to synthesize the system inputs (electrical constraints) from the outputs (aerodynamic torque and position of the flight control surface) given by data stored during an actual "flight mission". The particular issues of filtering and of synthesis by model inversion are discussed and a first simulation set is provided to illustrate the apabilities of this approach by means of BBGs. Then, the same process is applied to a more complete modeling of the EHA with a BG including several non linearities inside the electro hydrostatic transmission line.
