Low-Thrust Control of Lunar Orbits
A method is presented for the control of lunar orbiters using continuous low-thrust propulsion. While the proposed approach is fairly general and could be useful for a variety of mission scenarios, in this work it is applied to the partic-utar case of obtaintng a lunar Sun-synchronous orbit for use in a lunar mapping mission. Using optimal control theory, it is shown that a lunar orbit can be obtained that is low-altitude, near-polar, and Sun-synchronous. The analytis of the optimal control probtem leads to the commonly seen two-point boundary value problem, which is solved ustng an indirect shoottng algorithm.
