Abstract
This paper presents an optimal guidance approach
for a UAV point-to-point navigation in 2D, under wind perturbation, with
a general desired airspeed profile. A cost function weighting the travel
time and the control effort is minimized through the Pontryagin's
Minimum Principle, involving the derivatives of the airspeed velocities.
Two iterative procedures for a guidance algorithm under general wind
fields were developed, including an analytical solution for the optimal
heading in minimum-time paths. Different cases from the literature are
compared and a hard wind scenario test is presented.
