研究了多航天器姿态协调控制问题。利用李亚普诺夫直接法设计了一种简单的分散变结构协调控制器。在存在模型不确定性、外部干扰和通信时变时滞的情况下，所设计的控制器能够使编队飞行器在全局收敛的意义下保持姿态一致.借助于Barbalat引理的推论，从理论上证明了所设计的控制器对闭环系统的收敛性。数值仿真也包括证明所开发的控制器的性能。(C)2007 Elsevier B.V.保留所有权利。
The attitude coordination control problem for multiple spacecraft is investigated in this paper. A simple decentralized variable structure coordinated controller is proposed using Lyapunov's direct method. In the presence of model uncertainties, external disturbances and time-varying delays in the intercommunication, the presented controller can render a spacecraft formation consistent to a prespecified orientation in the globally-convergent sense. By virtue of a corollary of Barbalat's Lemma, the convergence of the proposed controller for the resulting closed-loop system is proved theoretically. Numerical Simulations are also included to demonstrate the performance of the developed controller. (C) 2007 Elsevier B.V. All rights reserved.
