Abstract

In the final proximity of rendezvous, linear H <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</inf> and nonlinear H <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</inf> control method are adopt for orbital tracking control and attitude tracking control respectively. We use the same thrusters system to implement orbital and attitude control command simultaneously. Because of the coupling caused by implementation, orbital control and attitude control command may conflict; we adopt a logic coordination method to avoid this situation. To the best of our knowledge, this is the first solution for orbital and attitude coupling control by the same implementation system in the final proximity of rendezvous. Numerical simulation verifies the validity and feasibility.
