Optimal Control Of Tethered Satellite Recovery

The concept of tethered satellite system consists of two or more satellites connected bythin and long cables. This dissertation focuses on the dynamics and control problemsconcerning tether recovery, which may be the most important but also delicate parts of aTSS mission.This paper proves the existence of the optimal control problem of tetheredsatellite system recovery, and establish the first order conditions of the optimal control ofthe optimal control problem, namely the Pontryagin maximum principle, we use themodified Euler method to get the numerical solution of optimal control.
