Distributed finite-time attitude containment control for multiple rigid bodies
Distributed finite-time attitude containment control for multiple rigid bodies is addressed in this paper When there exist multiple stationary leaders we propose a model-independent control law to guarantee that the attitudes of the followers converge to the stationary convex hull formed by those of the leaders in finite time by using both the one-hop and two-hop neighbors information We also discuss the special case of a single stationary leader and propose a control law using only the one-hop neighbors information to guarantee cooperative attitude regulation in finite time When there exist multiple dynamic leaders a distributed sliding-mode estimator and a non-singular sliding surface were given to guarantee that the attitudes and angular velocities of the followers converge respectively to the dynamic convex hull formed by those of the leaders in finite time We also explicitly show the finite settling time (C) 2010 Elsevier Ltd All rights reserved
