摘要
共面绕飞卫星的相对运动轨迹是一个椭圆,由于卫星受摄动力影响,其编队构形会发生变化。提出一种基于组合机动的队形保持策略,即在Hill轨道坐标系中,通过测量绕飞卫星相对位置,利用切向脉冲推力与径向连续常推力进行组合控制,消除相对运动椭圆中心的相位漂移。考虑地球扁率J2项摄动的影响,在队形保持中引入J2相对摄动加速度以提高控制精度。仿真结果表明,该控制方法能对共面卫星编队的空间构形进行有效保持。
The figure of the relative kinematical track of the coplanar flying-around satellites is an ellipse. However, the configuration of the formation flying will change because of the disturbing force. A new formation keeping strategy based on combined maneuver was developed. In Hill orbital coordinates, through the measurement of the relative position components of the flying-around satellites, the combined control of the tangential impulse thrust and the coastant continuous radial thrust eliminated the phase excursion of the center of the relative kinematical ellipse. Then the method considering the J2 perturbations was applied to improve the control accuracy. Simulation results show that this control strategy has nice performance on formation keeping.
