چکیده
The least squares method has been applied to estimate parameters in an aerodynamic model of a simulated aircraft, using data that can be expected to available from sensors on an Unmanned Aerial Vehicle. A combination of two non-linear state observers have been implemented to estimate wind data such as angle of attack, sideslip and dynamic pressure. Simulations have confirmed that the observers are able to estimete the wind data using noisy sensor measurements. Parameter estimation have been demonstrated with both measured and estimated wind data. Sammendrag Miste kvadraters metode har blitt brukt til å estimere parametere i en aerodynamisk model til et simulert fly, ved bruk av sensordata som kan forventes å finnes p̊a et ubemannet fly. En kombinasjon av to ulinære observere har blitt implementert for å estimere vinddata som angrepsvinkel, sideslipp og dynamisk trykk. Simuleringer har bekreftet at estimering av vinddata kan gjøres ved bruk av støyette sensorm̊alinger. Parameterestimering har blitt demonstrert ved bruk av b̊ade målte og estimerte vinddata.
