Abstract

In the last years air traffic density has increased all over the world. This calls for new tools to support the overworked controllers in the air traffic control centers. In this article an approach to compute optimal feedback-controls in realtime will be described. As a prerequisite a previously computed flight path is needed. Because of unforeseeable events like delays or environmental influences the controlled planes will leave this path in almost any case. Therefore it is necessary to update the computed trajectory to adapt it to the present conditions. To get the updates for the controls the known nominal trajectory and the actual state of the controlled object is used. The new idea is to not only adapt the controls, but also the reference path in every correction step. This yields an increase in robustness but on the other hand this raises the computational efforts. To reduce the time needed a parallel algorithm has been developed.
