Abstract. In the International Civil Aviation Organization, an important area is the development of new approaches to constructing and maintaining effective aircraft flight paths. Developing a flight control system capable of not only stabilizing the position, but also accurately tracking the trajectory for an aircraft is a rather complex task. In this paper, an algorithm for generating trajectory tracking control is proposed based on the methods of optimal control theory (OCT) using optimal filtering theory (OFT) approaches to estimate the trajectory motion parameters. The formulation of an autonomous optimal control problem is considered. In the paper, the flight route maintenance quality indicator is formulated as minimizing the deviation of the actual flight path from the specified one. The expediency of implementing the proposed approach is confirmed by the methods of simulation statistical modeling. To test the validity of the proposed approach, a simulation modeling of a typical flight path tracking under expected operating conditions was performed. Analysis of the results obtained during the simulation modeling shows that the deviation of the controlled flight path parameters from the specified values does not exceed 5Β m. The results demonstrate the efficiency of the algorithm for tracking a specified flight path and its stability to external disturbances.

Keywords: aircraft, flight path, Kalman filter, optimal control, optimal filtering, global navigation satellite system, trajectory control system.
