Electrical actuators are arriving onboard aircrafts. At the same time, computer simulations are more and more used to realize pre-studies concerning systems on board aircrafts. In this context, actuator models are needed. The objective of this paper is to present how an actuator can be modeled with the Bond Graph method. A complete Electro-Hydrostatic Actuator is modeled, from the electrical power supply to the flight control surface. To perform electrical network simulations, Saber software is greatly used in aeronautic. The Bond Graph model is therefore translated into an equivalent electrical circuit to use it directly on Saber. A validation is achieved with a reference model. Due to the adaptability of a Bond Graph design, the actuator model's accuracy can be easily fixed to the desired level.
