Real-Time Optimal Guidance with Application to Lifting Re-Entry Vehicles.
Abstract
A real-time optimal guidance scheme based upon the variation of extremals algorithm for obtaining optimal trajectories was formulated in two phases and applied to a planar lifting re-entry problem. First the variation of extremals algorithm was formulated and used in conjunction with a flexible prediction technique to construct an algorithm for rapidly generating optimal trajectories. Then, based also upon the variation of extremals algorithm, an en route optimal guidance algorithm was developed for guiding a vehicle to desired terminal conditions in the presence of perturbations.
