This paper aims at developing a novel fast attitude maneuver framework for optical remote sensing satellites subject to multiple uncertainties and limited control energy. The proposed framework relies on a two-layer approach, where the first layer provides the agile attitude planning which enforces the satisfaction of the control energy constraint, whereas the second layer, named the special fast maneuver controller, ensures the high-precision attitude tracking by suitably manipulating the agile attitude planning information. In addition, a novel disturbance observer is introduced into the scenario to enhance the robustness of the proposed fast maneuver controller against multiple uncertainties. The uniform ultimate boundedness of the proposed method is analyzed rigorously with the Lyapunov theory. To demonstrate the effectiveness, the proposed method is applied to the fast attitude maneuver of both simulated and real Jilin-1 GaoFen-02 satellite, which shows excellent control performance despite multiple uncertainties and limited control energy.

本文旨在为受多重不确定性和有限控制能量的光学遥感卫星开发一种新的快速姿态机动框架。所提出的框架依赖于两层方法，其中第一层提供敏捷姿态规划，强制满足控制能量约束，而第二层称为特殊快速机动控制器，通过以下方式确保高精度姿态跟踪适当地操纵敏捷姿态规划信息。此外，在场景中引入了一种新的干扰观测器，以增强所提出的快速机动控制器对多种不确定性的鲁棒性。采用李雅普诺夫理论对所提方法的统一极限有界性进行了严格分析。为了证明有效性，
