摘　　要：为了避免控制力矩陀螺在大角度姿态机动过程中的饱和,规划了最优的姿态机动路径,使大角度姿态机动过程中控制力矩陀螺的角动量峰值最小。建立了姿态机动的动力学与控制数学模型及姿态路径规划的数学模型,采用直接打靶法将控制路径规划问题转化为带参数约束的非线性参数优化问题,采用序列二次规划算法进行求解。数值仿真的结果表明通过姿态路径规划可以使大角度姿态机动过程中的控制力矩陀螺的角动量远离饱和。In order to avoid Control Moment Gyroscopes（CMGs） saturation during large-angle attitude maneuver,an optimal path is planned to minimize momentum peak.The models of attitude maneuver dynamic and control,as well as the path planning are established.The problem of path planning is transformed to a problem of non-linear parameter optimization by the use of the direct shooting method.Optimums are obtained by using sequential quadratic programming.The numerical simulation results indicate that through path planning,CMGs saturation can be avoided during large-angle attitude maneuver.
