Modeling and Simulation of The UX-6 Fixed-Wing Unmanned Aerial Vehicle

The flight model plays an important role in the development of the fixed-wing unmanned aerial vehicle (UAV)'s control system. By using the flight model, aircraft motion characteristics could be identified. Therefore, this modeling method is very important in speeding up parameters tuning of autonomous control systems and also to improve safety. The objective of the present research was to build The UX-6 fixed-wing UAV flight models with two approaches. First, the UX-6 UAV model was built analytically by using Datcom + Pro software. Meanwhile, the second model was built empirically based on flight data system identification. Both approaches were compared and analyzed in longitudinal and lateral flight modes. This work observed eight model's parameters, four in longitudinal modes and four in lateral modes. The parameters comparison demonstrated that five analytical model parameters have similar characteristics with empirical model parameters. Three model parameters had different characteristics, therefore, need to be improved. These parameters comparison results indicate that the model can represent the UX-6 UAV aircraft motion characteristics.
