Özet

© 2021, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.This paper focusses on performing analysis and comparison of three different approaches for input prediction of a fixed-wing aircraft following a known trajectory. Each of these approaches relies on different assumptions. Two of the approaches assume zero side-slip angle while the third one does not. For each approach, the analytical investigation of kinematic relations between the Euler angles of body-fixed frame, Euler angles of wind frame, and aerodynamic angles and path angles are shown. By using the kinematic relations between these angles, the control inputs which are required for the execution of a predefined trajectory or maneuver are determined. Numerical case studies are illustrated and the results are discussed.
