中文摘要 |
以微小卫星集群实现小行星探测为背景,研究局部信息交互的空间目标观测任务构形调整。针对难以直接求取集群构形调整的全局最优解问题,利用通信协调图,将全局协调决策分解成多个局部求解问题,并引入强化学习机制实现求解。针对集群全局协调决策问题,通过设计基于Max-plus算法的全局协调决策算法来实现全局协作;针对单星局部优化问题,设计基于神经网络的局部Q学习算法来实现单星动作调整规划。仿真结果表明,本文所提的协作规划算法能自主有效地将集群调整至期望构形,实现协同观测任务。 |
英文摘要 |
This paper investigates the problem of configuration adjustment of spatial target observation tasks for local information interaction during the deep space exploration mission of the microsatellite cluster. In order to solve the problem of directly solving the global optimal difficulty of cluster configuration adjustment, this paper uses the communication coordination diagram to decompose the global coordination strategy into multiple local solution problems, and the reinforcement learning mechanism is introduced to realize solution. Aiming at the global coordination decision-making problem of cluster, the cooperative interaction in the local learning process is realized by designing the global coordinated decision algorithm based on Max-plus algorithm. Aiming at the local optimization problem of individual satellite, a local Q learning algorithm based on neural network is designed to realize the adjustment action planning of each satellite. The simulation results show that the proposed planning algorithm can independently and effectively adjust the cluster to the desired configuration to realize the observation task collaboratively. |
