A Fuel Conservation Near-Optimal Control Law for an Evading Spacecraft.

Abstract

A fuel conservation control law for an evading spacecraft is tested in a free final time, pursuit-evasion differential game. A form of differential dynamic programming with periodic updating is used to solve the optimal control problem. The control law is tested against two different finds of pursuers. One of the pursues is using the same updating of the optimal control scheme and the other pursuer is using a non-optimal control law. The non-optimal control law produces a collision course between the two craft. The evader is able to take advantage of any non-optimal play by the pursuer. The evader is able to optimize the combination of final range and final mass, depending on the mission. Plots comparing the flight path of the evader and several different pursuers are included.
