小卫星姿态大角度机动联合控制算法

由于星上能源需求、空间目标探测和地面目标跟踪定向的要求，小卫星必须具备姿态大角度机动能力．基于磁力矩器和反作用飞轮联合控制，提出了一种绕瞬时欧拉轴旋转的机动控制算法．该算法根据运动学原理规划姿态机动的时间最短轨迹设计控制器进行跟踪，以实现时间较短的姿态大角度机动控制．仿真结果表明，算法鲁棒性好，设计简单且易于在轨实时计算，显著减少了反作用飞轮在机动过程中的饱和机会．

Combined control algorithm for large angle maneuver of small satellite

Large angle maneuver is required for power supply, special object detection and ground object capture on small satellite. From a combined control algorithm with magnetorquer and reaction wheel,an instantaneous-turn-axis control algorithm is proposed for initial and final states of the maneuver. The optimal maneuver track is obtained to access short maneuver time with the limit of reaction wheel's saturation characteristic according to the kinematics and, a controller is then designed to approach it. Simulation results indicate that the control algorithm has the excellent robustness and can be easily designed and realized.
