AI 中文摘要
当光敏仪器必须避开明亮物体时，航天器姿态控制变得具有挑战性。本工作提出一种基于路径规划的航天器姿态重定向机动方法，考虑这些约束以达到期望姿态。在姿态空间中，采用模糊增强势场方法计算满足约束的姿态轨迹。基于路径规划输出，通过考虑航天器的动力学和运动学来确定控制输入，以满足时域内的动态约束。数值仿真结果表明，在不违反约束的情况下成功实现了重定向机动。
英文摘要
Spacecraft attitude control becomes challenging when light-sensitive instruments must avoid bright objects. This work proposes a path-planning-based spacecraft attitude reorientation maneuver considering these constraints to reach the desired attitude. Constraint-compliant attitude trajectories are computed using a fuzzy enhanced potential field approach in the attitude space. Based on the path-planning output, the control input is determined by considering the dynamics and kinematics of the spacecraft to satisfy dynamic constraints in the time domain. Numerical simulation results demonstrate successful reorientation maneuvers without violating the constraints.
