Modal Control of a Satellite in Orbit about L3.

Abstract

A modal control scheme was developed for linear systems that are time periodic. The scheme was then applied to a satellite in orbit aobut the earth-moon Lagrange point, L3. A theoretical control gain prediction was also devised and then verified by numerical results. The feasibility of the control scheme was then verified by computer simulations by controlling the actual non-linear motions of the satellite with the linearly derived controller. The satellite control costs were found to be 30 percent less than the control costs of a satellite in earth-synchronous orbit. (Author)
