| 摘 要： | 分析了大气阻力对近地轨道卫星轨道参数的影响,用变结构控制设计了基于大气阻力的编队构型沿航迹方向的控制。将中心的漂移距离和编队卫星的面质比之差作为输入量,设计滑模面进行编队控制,用极限环方式消除了在滑膜面附近的频繁切换。仿真结果验证了该控制律的正确性。

| Abstract: | The effect of the atmosphere drag on the orbit parameters of the low earth satellite was analyzed in this paper. The control of the in-track drift of the formation configuration was designed by using various control method based on the atmosphere drag. The drift if the center and the difference of the area-mass ratio between the formation satellites were served as the input to design the sliding mode for controlling the formation. The problem that the structure switched frequently was solved by designing margin circle： The simulation results showed that this control law was correct. |
