Problem statement. In the process of aiming an aircraft at a target under the influence of a large number of factors, its deviation from a given kinematic trajectory is possible. In this case, it is necessary to ensure the transfer of the aircraft in the minimum time to the required parametric state. Goal. Development and evaluation of the characteristics of an optimal algorithm for trajectory control of an aircraft that minimizes the transition time to the required state while limiting the amount of available lateral acceleration. Results. In accordance with the Pontryagin maximum principle, an algorithm for trajectory control of an aircraft has been developed that is optimal according to the criterion of the minimum time for testing its deviation from the required kinematic trajectory. Analytical expressions are obtained for the control signal, its switching time points, switching function, as well as controlled phase coordinates without taking into account the inertia of the aircraft guidance contour and changes in the radial parameters of the relative movement of the target. In the interest of increasing the visibility of the algorithm, the direct guidance of the aircraft to a remote stationary target in one plane is considered. A comparative analysis of the effectiveness of aircraft guidance using the proposed and well-known optimized trajectory control algorithm is carried out. The directions of further research are formulated. Practical significance. The simulation results allow us to conclude that it is expedient to use trajectory forced control of the aircraft with restrictions on the magnitude of the control signal to minimize the time of working out the required phase coordinates.
