针对小天体柔性着陆任务规划中的复杂耦合时间约束一致性推理效率问题,建立任务规划时间约束网络,通过划分时间约束类型,设计约束动态添加策略,提出动态弧一致时间约束推理方法,限制新添加约束的传播范围,局部求解时间网络一致性,实现规划过程中时间约束网络一致性的高效维护.最后,构建小天体着陆规划场景,生成着陆任务规划活动及时间约束.仿真结果表明,与现有时间约束推理方法相比,所提出方法提高了时间约束推理效率,进而可为小天体柔性着陆任务规划提供支撑.
Dynamic Temporal Constraint Reasoning Method for Flexible Landing Mission Planning of Small Celestial Body
To address the complex coupled temporal constraint consistency reasoning problem in the planning of the small celestial body flexible landing mission,a mission planning temporal constraint network is constructed,temporal constraint types are classified,and a constraint dynamic addition strategy is established.A dynamic arc-consistent temporal constraint reasoning method is proposed to limit the propagation range of newly added constraints,locally solve the temporal network consistency,and maintain the temporal constraint network in the planning process dynamically.Finally,a small celestial body landing planning scenario is designed with the landing planning activities and temporal constraints.Simulation results show that compared with the existing temporal constraint reasoning method,the method in this paper improves the computational efficiency,which supports the planning of small celestial body flexible landing missions.
