The possibility of simplifying the mathematical model of aircraft motion, used to design an adaptive controller based on the principle of dynamic inversion, is considered. The effectiveness of a controller synthesized using such a simplified model is tested in standard piloting conditions and in the case of a pilot–aircraft system failure. To assess the accuracy of a tracking task for different variants of controller synthesis, flight simulator-based experiments were carried out.
