摘　　要：针对近地轨道编队飞行卫星的构形保持控制问题,引入相对轨道根数描述编队构形参数,通过补偿控制过程中的耦合影响,优化设计三脉冲编队保持控制方法和相应的控制策略。仿真中考虑了相对导航误差、推力器的推力大小和方向偏差、测控条件约束等因素的影响,并分析了编队保持控制的特点以及控制精度。研究结果表明:该方法简单有效,具有工程应用价值。Aim to the formation-keeping control issue of formation satellites flying in low earth orbit, a control method of three-impulse formation-keeping control was studied in this paper. The three pulse formation-keeping method and corresponding control strategy were optimized by introducing the relative orbit elements to describe the formation configuration parameters and compensation the coupling effect during the control procedure. The influences of the relative navigation errors, the force and direction deviation of thruster, the limitation of track and control capabilities were considered in the simulation. The control characteristic and precision of the formation- keeping control method were analyzed during the simulation. The simulation results showed that the control method was simple and effective, which was valuable for engineering application.
