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。
The influence of atmospheric resistance on orbit parameters of near-Earth orbit is analyzed, and the control of formation formation along the track based on the atmospheric resistance is designed with variable structure control. The drift distance of the center and the difference between the mass ratios of the formation satellites are taken as input variables, and the sliding mode control is designed for formation control. The limit cycle method is used to eliminate the frequent switching around the synovial plane. Simulation results verify the correctness of the control law.
