Subsumption architecture applied to flight control using composite rotations
(Peer reviewed; Tidsskriftartikkel; Journal article, 2016-03-19)
In this paper the subsumption theory is applied to flight control through composite rotations where multiple tasks can be defined as simple rotations. The tasks can then be arranged as a hierarchy, where the primary task is always fully pursued, and conflicting lower level tasks are removed by the primary rotation. The concept is applied to a group of uavs that move through an urban terrain while ...
A Decoupled Approach for Flight Control
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
A decoupling method for flight control is presented that greatly simplifies the controller design. By approximating the higher order derivatives of the angle of attack and sideslip, it enables a rotation controller and a speed controller to be derived independently of each other, and thus gives access to a vast number of controller solutions derived for general classes of rotational and translational ...
