Nowadays the use of complex models has increasedthe requirements of the simulation tools and techniques forworking and analyzing with different domains at the sametime. This work focuses on the study of the Scannerservocontrols of a fighter aircraft. The model has the feature ofintegrating various physical domains into the same system(electrical, mechanical and system control environments) withdifferent dimensions in each domain. The technique used is theBond Graph (BG), which is typically used in fields wheredifferent physical domains coexist, just as in the case we aredealing with, where such domains are fundamental. At thebeginning of the study, the different coordinate references areintroduced and the physical subsystems are also described.After this the different subsystems are presented in the form ofBG 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.
