The effect of lift on aeroassisted orbital transfer trajectories
Miele, Wang, and Deaton have demonstrated in Ref. 1 how optimal trajectories are produced by eliminating positive lift and fixing the lift coefficient at its lower, negative (downward) bound all throughout the atmospheric ...
Comparison of gradient-restoration algorithms for optimal control problems with nondifferential constraints and general boundary conditions
The problem considered here involves a functional I subject to differential constraints, nondifferential constraints, and general boundary conditions. It consists of finding the state x(t), control u(t), and parameter $\pi$ ...
