摘要
对萤火一号(YH-1)火星探测器姿态控制分系统设计进行了研究。介绍了分系统的特点与组成、控制模式,设计了基于四元数的反馈控制律。采用的绕空间任意欧拉轴机动的控制方案可实现4π空间内的机动,且有较高的自主性,以确保探测器在轨运行的安全。地面模拟飞行试验验证了器上自主控制等措施。
The design of the attitude control subsystem for YH-1 Mars probe was studied in this paper. The characteristics, composition and control mode of the subsystem were given out. The quaternion feedback control algorithm was designed. The control algorithm by moving round any Eular axis in the space could move to any direction in the 4π space, which was high autonomous to ensure the on orbit operation security of YH-1 Mars probe. YH-1 Mars probe＇ s autonomously control algorithm had been proved the availability by simulation the flying on obit.
