The thesis work is focused on the model identification of an UAV (unmanned aerial vehicle) in straight steady flight condition, based on input-output data collected from flight tests using both frequency and time domain techniques. The vehicle used for this work is an in-house 40 cm wingspan airplane. Because of the complex coupled, multivariable and nonlinear dynamic of the aircraft, linear SISO structures for both the lateral and the longitudinal model around a reference state were derived. The aim of the identification is to provide models that can be used in future UAV applications that involves the implementation of control techniques.
Basically the presentation is about general models for UAVs, linear models for flight conditions, hardware and software designed for model identification experiments and results regarding a specific vehicle: The 40 cm wingspan UAV designed and built in UGent. Some references about possible control strategies are given.
