中文摘要：
研究存在输入饱和受限下的飞行器姿态控制问题,提出一种有限时间姿态镇定方案.针对基于修改的Rodriguez参数模型的飞行器姿态控制系统,基于齐次性理论和饱和控制器设计方法,并充分利用系统的模型结构特征,设计一类饱和的有限时间姿态控制器,使得姿态可以在有限时间内被镇定到平衡点.仿真结果验证了所设计姿态控制器的有效性.
英文摘要：
The problem of finite-time attitude stabilization of a rigid spacecraft under input saturation is investigated. For the attitude control model described by modified rodriguez parameters, based on homogeneous system theory and saturated controller design method, a saturated finite-time attitude control law is proposed, which sufficiently uses the model structural features, so that the attitude can be stabilized to the equilibrium in a finite time. Simulation results show the effectiveness of the proposed method.
