Abstract:
In this thesis, an identified dynamic model of a fixed wing UAV, known as WAYO, is presented. To do so, frequency domain system identification technique is utilized. Due to physical and environmental constraints, it was impossible to carry out precise flight tests of the aircraft in all flight phases. Instead, a small-sized UAV, called Twin Star-BL was selected to carry out the tests and to validate the simulation model. In both cases (WAYO and Twin Star-BL) transfer functions were obtained using frequency responses and employing extensive identification process. Identified models were then assessed using time domain data for different test records. Finally, handling qualities of both aerial vehicles were obtained using identified models and relevant standards
