Abstract
The purpose of this research is to estimate the dimensional stability derivatives in linear
dynamic model of a fixed-wing model-scale unmanned aerial vehicle (UAV) by real flight data
logged by an onboard flight computer. The paper described the experimental setup, operation
procedure of raw flight data, process of nonlinear least squares estimation, and cause-effect
examination of impulse responses. The simulation-based results of the estimated model indicated a
very good accuracy with real flight data. The linear longitudinal and lateral models are very helpful
for designing the stability-augmentation system or autopilot for the UAV.
