研究了偏心率/倾角(E/I)联合隔离方法在卫星编队安全轨迹设计和保持控制中应用。首先,引入E/I矢量和相对E/I矢量,建立了相对E/I矢量描述的相对运动方程。然后,分析了摄动对相对E/I矢量和编队安全性的影响,得到了安全性要求下相对E/I矢量需要满足的条件;推导了E/I联合隔离控制方程,提出了安全轨迹保持控制策略。最后,通过仿真验证了基于E/I联合隔离的安全轨迹设计与控制策略的有效性。
The eccentricity / dip (E / I) joint isolation method was applied to the design and maintenance of satellite formation safety trajectory. First, we introduce the E / I vector and the relative E / I vector to establish the relative motion equation described by relative E / I vector. Then, the influence of perturbation on the relative E / I vector and formation safety is analyzed, and the conditions that the relative E / I vector needs to be satisfied under the safety requirement are obtained. The E / I joint isolation control equation is deduced, and the safety track keeping Control Strategy. Finally, the effectiveness of safety trajectory design and control strategy based on E / I joint isolation is verified by simulation.
