针对偏置动量卫星的特点,提出了一种偏置动量卫星东西位置保持策略优化方法。根据单自由度轮控系统的控制方式、角动量管理的控制方法,以及角动量管理对卫星轨道的影响,基于动量轮转速的变化建立了推力器喷气效率、轨道元素变化量计算模型,提出了可延长东西位置保持周期的轨道控制优化策略。实际轨控任务应用结果表明方法控制效果良好。
Aiming at the characteristics of offset momentum satellite, an optimization method of position keeping strategy of offset momentum satellite is proposed. According to the control method of single degree of freedom wheel control system, the control method of angular momentum management and the influence of angular momentum management on the satellite orbit, a model to calculate the change of propeller efficiency and orbit elements is proposed based on the variation of momentum wheel speed. Orbital control optimization strategy that can extend the location retention period of things. The actual rail control mission application results show that the method control effect is good.
