Abstract

This article is about the algorithm for finding optimal solution of the problem of high precision homing on the terminal part of the trajectory for high-speed aeroballistic unmanned aerial vehicle (UAV) with high aerodynamic efficiency into the atmosphere. The described algorithm, in essence, is solution for nonlinear optimal control problem with some of unique features. The mentioned problem is complicated by the uncertainties of aerodynamic characteristics of the aircraft and the wide range of uncontrolled effects of the different nature. The algorithm generates aboard continuously updateable optimal trajectory in the form of numerical determination of control inputs have obtained by variational methods according to the data from the multispectral surveillance system. The problem is solving within following constrains: on accuracy, absolute value and orientation of the velocity vector at the end of the path, total waste of control actions and resolution of the multispectral surveillance system. Simulation results show us the applicability of the proposed algorithm for generation of optimal control actions in different conditions with the low sensitivity to the effects of uncontrollable factors.
