Adaptive Observer and Kalman Filtering

Résumé

In this paper the problem of the speed estimation of an Unmanned Aerial Vehicle is addressed, when only the standard outputs (acceleration, angles and angular speeds) are available for measurement. We focus our analysis on a prototype drone - a 4 rotors helicopter robot- which is not equipped with GPS related devices and relies on the Inertial Measurement Unit (IMU) only. Two different approaches have been compared. The first one uses a classical method based on Kalman Filtering while the second solution is provided in the frame of adaptive observation theory. These estimators have been tested in two situations : when exact measurements are available and in the more realistic case of noisy acceleration measurements.
