用学习增强的磁控算法实现多星编队稳定控制,实验验证了其可扩展性与安全性。

NODA-MMH: Certified Learning-Aided Nonlinear Control for Magnetically-Actuated Swarm Experiment Toward On-Orbit Proof

  • 基于学习的时序电流控制提升系统可控性,理论保证误差上限
  • 在空气轴承平台上实现三颗以上卫星的磁力编队实验,验证了去中心化控制
  • 提出可认证的最优功率磁矩分配方法,适合长期在轨编队任务

本研究通过实验验证了利用卫星上磁力矩器生成磁场交互作用来实现大规模卫星编队控制的可行性。该推进方式为多星长期编队维持提供了有前景的解决方案,此前仅在地面试验台上完成过双星位置控制验证。当卫星数量超过三颗时,高非线性带来四大挑战:非完整约束、欠驱动、可扩展性及计算成本。已有研究表明,时间积分电流控制理论上可解决这些问题,使平均执行器输出与期望指令对齐,结合学习技术可进一步提升性能。通过多次实验,验证了学习增强的时间积分电流控制的关键优势:(1) 提升平均系统动力学的可控性,且具有理论保证的误差界;(2) 实现去中心化电流管理。设计了双轴线圈与基于空气轴承平台的地面实验系统,可数学复现轨道动力学。基于学习到的交互模型,提出NODA-MMH(Neural power-Optimal Dipole Allocation for certified learned Model-based Magnetically swarm control Harness),用于基于模型的功率最优编队控制。本研究补充了我们关于磁控编队长期维持问题的教程论文。

原文摘要 · Abstract (English)

This study experimentally validates the principle of large-scale satellite swarm control through learning-aided magnetic field interactions generated by satellite-mounted magnetorquers. This actuation presents a promising solution for the long-term formation maintenance of multiple satellites and has primarily been demonstrated in ground-based testbeds for two-satellite position control. However, as the number of satellites increases beyond three, fundamental challenges coupled with the high nonlinearity arise: 1) nonholonomic constraints, 2) underactuation, 3) scalability, and 4) computational cost. Previous studies have shown that time-integrated current control theoretically solves these problems, where the average actuator outputs align with the desired command, and a learning-based technique further enhances their performance. Through multiple experiments, we validate critical aspects of learning-aided time-integrated current control: (1) enhanced controllability of the averaged system dynamics, with a theoretically guaranteed error bound, and (2) decentralized current management. We design two-axis coils and a ground-based experimental setup utilizing an air-bearing platform, enabling a mathematical replication of orbital dynamics. Based on the effectiveness of the learned interaction model, we introduce NODA-MMH (Neural power-Optimal Dipole Allocation for certified learned Model-based Magnetically swarm control Harness) for model-based power-optimal swarm control. This study complements our tutorial paper on magnetically actuated swarms for the long-term formation maintenance problem.
