Abstract

Space object observation requirements and the avoidance of specific attitudes produce pointing constraints that increase the complexity of the attitude maneuver path-planning problem. To deal with this issue, a feasible attitude trajectory generation method is proposed that utilizes a multiresolution technique and local attitude node adjustment to obtain sufficient time and quaternion nodes to satisfy the pointing constraints. These nodes are further used to calculate the continuous attitude trajectory based on quaternion polynomial interpolation and the inverse dynamics method. Then, the characteristic parameters of these nodes are extracted to transform the path-planning problem into a parameter optimization problem aimed at minimizing energy consumption. This problem is solved by an improved hierarchical optimization algorithm, in which an adaptive parameter-tuning mechanism is introduced to improve the performance of the original algorithm. A numerical simulation is performed, and the results confirm the feasibility and effectiveness of the proposed method.

最小能量航天器姿态机动路径规划的自适应连通分层优化算法

空间物体的观测要求和对特定姿态的回避产生了指向约束，增加了姿态机动路径规划问题的复杂性。针对这一问题，提出了一种可行的姿态轨迹生成方法，该方法利用多分辨率技术和局部姿态节点调整来获得足够的时间和四元数节点来满足指向约束。这些节点进一步用于基于四元数多项式插值和逆动力学方法计算连续姿态轨迹。然后，提取这些节点的特征参数，将路径规划问题转化为以最小化能耗为目标的参数优化问题。该问题通过一种改进的分层优化算法来解决，其中引入了自适应参数调整机制来提高原有算法的性能。通过数值模拟验证了该方法的可行性和有效性。
