Unmanned Aerial Vehicle Speed Estimation via Nonlinear Adaptive Observers

Abstract: In this paper the problem of the speed estimation of an Unmanned Aerial Vehicle is addressed, when acceleration, the angles and the 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. A global exponential solution to this open problem is provided in the framework of adaptive observation theory when exact measurements are available. A modified e… Show more

“…Recently, Bonnabel, Martin, and Rouchon (2006), Vik and Fossen (2001), Zhao and Slotine (2005), Benallegue et al (2008), Besnard et al (2007), Boutayeb et al (2008), Benzemrane et al (2007), Benzemrane (2009), Madani and Benallegue (2007) and Pflimlin et al (2007) have proposed observers to be implemented on UAVs. The critical issue in this domain comes from the fact that the translation velocity is classically known as non-observable.…”

“…Taking advantage of this observer, a feedback linearization controller [27] and a back-stepping controller [28] are employed to achieve MAV position tracking control in the presence of external disturbances. Nonlinear adaptive observer techniques are employed in [29] for velocity estimation of a quadrotor MAV, using noisy acceleration and angular measurements from IMUs, and the resulting observer demonstrates robustness to measurement noise in simulations. However, the proposed adaptive observer may be computationally demanding for onboard implementations since the cascade observer contains high-order terms.…”
