Title: Autopilot Design for Fixed Wing UAV
Author: Osman, Mohammed Abdelmoneim Ali
Abstract: Aerospace industry witnessed an enormous growth over the past few years. Due to reliability, cost and safety issues Unnamed Aerial Vehicle (UAV) became dominant over manned aircrafts. Unnamed aircrafts play a major role in nation’s development nowadays, the use of such aircrafts became not only important but also necessary especially in defense programs and defense strategies all over the world. Designing UAVs for commercial or military purposes is very challenging and implies highly accurate controllability and guidance requirements. By achieving these requirements a UAV will be of a full automatic control system. This thesis comprises a detailed successive loops methodology, which is used for designing and simulating controllers for both longitudinal and lateral behaviors for a six degrees of freedom fixed wing Ultrastick25-e aircraft. A brief overview of aircraft design process is presented with reference to flight simulation procedure. PID controller is designed and implemented over Ultrastick25-e mathematical model developed by University of Minnesota using MATLAB Simulink. Designed autopilot is then tested by comparing the simulation result of multiple types of inputs to another designed by University of Minnesota’s research group. Finally, an equivalent flight environment is implemented through software in loop (SIL) procedure. By using SIL actuators and sensor dynamics generated from a real environment are added thus validation of the designed autopilot is more acceptable.
