Quadrotor attitude estimation using adaptive fading multiplicative EKF
(Peer reviewed; Konferansebidrag; Conference object, 2017-07-03)
This paper presents the implementation of an adaptive fading multiplicative extended Kalman filter (AFMEKF), applied to the problem of attitude estimation in the context of quadrotors. The extended Kalman filter is adapted for use with quaternions and made adaptive to account for inaccurate measurement information. Simulations have been conducted in order to validate the filter performance.
Dual-quaternion backstepping control for a fully-actuated rigid-body
(Peer reviewed; Book; Chapter, 2018-08-16)
In this paper dual-quaternions are used to model a fully actuated rigid-body. A backstepping-controller that solves the trajectory tracking problem is derived and proved to provide uniform asymptotical stabilization of the error dynamics. Numerical simulations are provided where the controller is compared to existing dual-quaternion tracking controllers and it is shown to have similar performance.
