The numerical results are obtained for both a fixed and a variable attitude configuration.
The MPC policy enforces constraints that maintain the satellite in a tight latitude and longitude window and in a tight nadir-pointing attitude configuration, while minimizing the delta-v provided by the thrusters.
The proposed controller guarantees uniform almost global finite-time stability of the closed-loop system and produces a well-defined vector field on the attitude configuration manifold, thus avoiding the unwinding phenomenon.
