摘要
针对编队卫星的空间在轨服务任务,提出一种多类载荷异构星群的协同操作方案。首先,考虑星间自主通信,建立了由一颗主故障识别的观测卫星和多颗主维修补给的操作卫星构成的编队系统。其次,提出一种基于循环交替策略的多星协同轨迹规划方法,并基于差分进化算法优化了星群轨迹。最后,结合算例仿真,分析了系统内各成员卫星在编队控制过程中所需的脉冲大小以及编队系统整体的安全性能。仿真结果表明,异构编队系统可快速规划出安全性较高、鲁棒性较强的在轨服务轨迹,具有一定的工程应用价值。
In view of the on-orbit service mission using formation satellites,a cooperative operation scheme for the multi payload heterogeneous satellite cluster is proposed.Firstly,considering the inter-satellite autonomous communication,a formation system consisting of an observation satellite for main fault identification and several operational satellites for main maintenance and replenishment is established.Secondly,a multi-satellite cooperative trajectory planning method based on cyclic alternating strategy is proposed,and the satellite trajectories are optimized based on differential evolution algorithm.Finally,combined with case simulation,the impulses required by each member satellite in the formation control process and the overall safety performance of the system are analyzed.The simulation results show that the heterogeneous formation system can quickly plan the in-orbit service trajectory with high safety and robustness,which has certain engineering application value.
