航天器轨道规避的研究对航天器在轨运行安全问题有重要意义。针对航天器在轨运行安全的问题,根据航天器规避预警专家系统,在CLIPS环境下建立安全距离的预警专家系统模型,进行了航天器规避路径规划的研究,分别研究了预警专家系统的Lambert直接规避路径规划和航天器规避返回路径规划,并进行了数值仿真。仿真结果揭示了航天器规避机动时刻与所需燃料以及不同时间返回原轨道所需燃料的规律,使可预警航天器规避准确实时,为研究工作提供了依据。
Research on spacecraft orbit avoidance is of great significance to spacecraft in-orbit operational safety issues. Aiming at the problem of spacecraft orbital safety in operation, according to spacecraft early warning expert system, an early warning expert system model of safety distance is established in CLIPS environment, and the research of spacecraft avoidance path planning is carried out. The early warning expert system Lambert direct Avoidance path planning and spacecraft avoidance return path planning, and carried out numerical simulation. The simulation results reveal the regularity that the spacecraft avoids the maneuvering moment and the required fuel and the fuel needed to return to the original orbit at different time so as to make the preemptive spacecraft avoid the accurate real-time and provide the basis for the research work.
