Abstract :
In this paper we will derive feedback laws to stabilize the attitude motion of a rigid spacecraft in finite time. The laws are such that a cost functional measuring the overall angular velocity during the spacecraft motion is minimized. The implementation of these laws in an on-board attitude control system requires only autonomous attitude determination capabilities and no measurements of the angular velocities.
