深空探测器自主规划技术研究进展

Research Progress of Autonomous Planning Technology for Deep Space Probes

在深空探测过程中,探测器飞行距离远、所处环境动态多变,传统地面站遥测遥控方式很难满足探测器控制的实时性、鲁棒性和安全性等要求,迫切需要探测器具有自主性,而自主规划技术是实现探测器自主运行的核心技术之一。介绍了自主规划技术发展历程,给出了深空探测器自主规划内涵,分别从自主规划和执行框架、任务规划知识模型、任务规划和重规划、运动规划以及科学观测任务规划六方面进行总结和分析关键技术,并根据技术发展和任务需求,提出了深空探测器自主规划技术发展趋势和重点研究方向。

In the process of deep space exploration,the probe has a long flight distance and is in dynamic environment.Traditional ground station telemetry and remote control methods can hardly meet the requirements of real-time,robustness and safety of the probe control.It is urgent for the probe to have autonomy,and autonomous planning technology is one of the key technologies to realize the autonomous operation of the probe.The article introduces the development of autonomous planning technology and the connotation of autonomous planning for deep space probes,summarizes and analyzes key technologies from the framework of planning and execution,planning model,mission planning,replanning,motion planning and scientific observation mission planning,and proposes the development direction of autonomous planning based on technological development and mission requirements.
