TLDR
Rigorous proof shows that the desired attitude can be tracked in finite time in the absence of disturbances, and a distributed finite-time attitude control law is proposed for a group of spacecraft with a leader-follower architecture.Abstract:
This note investigates the finite-time attitude control problems for a single spacecraft and multiple spacecraft. First of all, a finite-time controller is designed to solve finite-time attitude tracking problem for a single spacecraft. Rigorous proof shows that the desired attitude can be tracked in finite time in the absence of disturbances. In the presence of disturbances, the tracking errors can reach a region around the origin in finite time. Then, based on the neighbor rule, a distributed finite-time attitude control law is proposed for a group of spacecraft with a leader-follower architecture. Under the finite-time control law, the attitude synchronization can be achieved in finite time.read more

The attitude control problem
TL;DR: In this article, a general framework for the analysis of the attitude tracking control problem for a rigid body is presented and a large family of globally stable control laws are obtained by using the globally nonsingular unit quaternion representation in a Lyapunov function candidate whose form is motivated by the consideration of the total energy of the rigid body.
