Simulation Model of the Scanner Servocontrols for the Orientation of a Fighter Aircraft by Using the Bond Graph Technique

Abstract

Nowadays the use of complex models has increased the requirements of the simulation tools and techniques for working and analyzing with different domains at the same time. This work focuses on the study of the Scanner servocontrols of a fighter aircraft. The model has the feature of integrating various physical domains into the same system (electrical, mechanical and system control environments) with different dimensions in each domain. The technique used is the Bond Graph (BG), which is typically used in fields where different physical domains coexist, just as in the case we are dealing with, where such domains are fundamental. At the beginning of the study, the different coordinate references are introduced and the physical subsystems are also described. After this the different subsystems are presented in the form of BG submodels one by one and the global Multibond Graph (MBG) model is displayed. Lastly, an example of simulation is shown and some important conclusions are reached.
