Considering the complex constraints like the performance of the actuators and the spatial pointing of the sensors,this paper studies the attitude maneuver trajectory planning problem for the space vehicles. The atti?tude maneuvering trajectory planning model was developed,and then mapped into the so?named flat output space via the differentially flat theory,eliminating the differential constraints and decreasing the design dimension. The pseudospectral method was utilized to parameterize the flat outputs, and the conformal map and barycentric ra?tional interpolation techniques were introduced to improve the ill?conditioning of the differential matrix such that the trajectory planning accuracy could be enhanced. Numerical simulation eventually verifies that the attitude ma?neuver trajectory under various constraints could be planned efficiently via the proposed method,providing some reference for the engineering application.%考虑执行机构性能、传感器空间指向等复杂约束,研究了空间飞行器姿态机动的路径规划问题.建立了姿态机动路径规划模型,并通过使用微分平坦理论将其映射到平坦输出空间,消除微分方程约束的同时降低设计空间维数;给出了平坦输出参数化描述的伪谱法,并运用共形映射、重心插值等技术改善了微分矩阵的病态特性,提高了路径规划的精度.仿真表明:该方法能够较快规划出满足约束的姿态机动路径,对工程应用具有一定参考价值.
