摘要
以某在轨GEO卫星为研究对象,探讨了适用于V型轮控系统特点的东西位置保持策略.首先分析了V型轮控系统的工作原理,提出了轮控过程中推力器效率的标定方法和喷气卸载对轨道影响的数学模型;然后深入分析了轮控过程中姿态控制对卫星东西位置保持环及偏心率的影响,提出了延长位保周期的控制策略,并在实际任务中获得了较好的效果.
An east-west station-keeping control strategy suitable for a V-wheel control systems is proposed for a GEO satellite in orbit. First, the V-wheel control system is analyzed and a calculation method to calibrate the thruster efficiency is derived. Then a model of the effect of momentum dumping on orbit is developed. The influence of attitude control on station-keeping rings and eccentricities is also studied in detail. Finally a control strategy is developed to extend the period of station-keeping control. The method is shown to be a success in practice.
