| Summary: | In this study, estimation of longitudinal aerodynamic parameters of a small
unmanned aircraft vehicle (UAV) is conducted using simulation data. As the first
step, a dynamics model of the UAV is developed by using previously developed data.
To generate flight test data, flight maneuver simulations are performed with certain
input. The flight variables of the UAV are recorded and added with noise to
simulate the characteristics of the sensors.
Digital filter is used to suppress measurement noise in the measured data. Some
flight variables which are not measured directly are reconstructed through
numerical differentiation and flight path reconstruction (FPR) process.
Estimation of longitudinal aerodynamic parameters is conducted using several
estimators, i.e. ordinary least squares (OLS) method, output error method (OEM),
and filter error method (FEM). The aerodynamic structure and parameters are
adjusted to the aerodynamic model used to make the dynamic model of the UAV.
Finally, validation and predictive ability test are conducted to the aerodynamic
models. |
