| Abstract | ||
| Nowadays Unmanned Aerial Vehicles (UAVs) have become one of the biggest interests in the whole world either in military applications or in the civilian one such as agricultural observation and traffic monitoring, also a major tendency in UAVs modeling has been increased due to the accurate mathematical modeling and open loop simulation are very important to understand the UAV behaviors for various inputs, accuracy of guidance and control design also depends on the accuracy of the open loop model. So, accurate UAV model is a crucial at all. Accuracy of UAV model depends on the accuracy of its subsystems. in this work a small fixed wing UAV Cessna is taken as a case study and an accurate modeling using experimental measurements of geometric and inertia mass model is performed, dynamic model is performed by using 6 DOF equation of motion, the atmospheric model is modeled through the international standard atmosphere (ISA). Finally, aerodynamic model is estimated using a semi-empirical method (DATCOM) by using the aircraft intitutive design (AID) application in MATLAB. These subsystems are integrated in a Simulink model in order to simulate the overall model. | ||
