  • 通过数据驱动层实时调节控制参数,提升复杂环境下的适应性。
  • 在模拟任务中比固定参数方法成功率更高,且全程保持安全距离。
  • 适合需要可解释性和高安全性的太空机器人自主控制场景。

在对抗性轨道环境中,自主交会与近距离操作需平衡目标追踪、安全防护和实时适应能力。现有学习方法因可解释性差、鲁棒性不足和约束感知弱,难以应用于高风险轨道机器人任务。本文提出一种自适应模型预测控制(MPC)框架,结合约束型滚动时域优化与数据驱动的监督调参层,基于离线闭环评估和在线交互几何信息动态调整控制器参数。相对运动遵循Clohessy-Wiltshire(CW)动力学,实现高效有限时域预测与实时二次优化。该框架包含执行器限制、预测型禁区约束、松弛变量可行性处理及可选控制屏障函数(CBF)安全过滤。不直接生成推力指令,而是调节可解释的MPC参数,如跟踪权重、安全惩罚、最小间距目标和禁区目标。在官方Kerbal Space Program Differential Game(KSPDG)捕卫星环境中的蒙特卡洛仿真表明,该方法显著提升闭环鲁棒性与机动适应性,相比固定参数MPC在保持安全性与实时可行性的前提下,实现更优的交会性能,为自适应航天器近距离操作提供模块化、可解释的技术基础。

原文摘要 · Abstract (English)

Autonomous rendezvous and proximity operations (RPO) in adversarial orbital environments require guidance architectures balancing target pursuit, safety preservation, and real-time adaptability under dynamically evolving interaction conditions. Although learning-based approaches show promise, their application to safety-critical orbital robotics remains limited by concerns regarding interpretability, robustness, and constraint awareness. This work presents an adaptive Model Predictive Control (MPC) framework for autonomous spacecraft RPO in multi-agent adversarial scenarios. The proposed architecture combines a constrained receding-horizon MPC formulation with a data-driven supervisory tuning layer that adjusts controller parameters from offline closed-loop evaluation and online interaction geometry. Relative motion follows Clohessy-Wiltshire (CW) dynamics, enabling computationally efficient finite-horizon prediction and real-time quadratic optimization. The MPC formulation incorporates actuator limits, predictive keep-out-zone constraints, slack-variable feasibility handling, and optional Control Barrier Function (CBF) safety filtering. Rather than generating thrust commands directly, the adaptive layer modifies interpretable MPC parameters, including tracking weights, safety penalties, minimum-separation objectives, and keep-out-zone objectives. The framework was evaluated in the official Kerbal Space Program Differential Game (KSPDG) Capture-the-Satellite environment through Monte Carlo simulations. Results demonstrate improved closed-loop robustness, adaptive maneuvering behavior, and rendezvous performance compared with fixed-parameter MPC while preserving safety-aware operation and real-time feasibility, providing a modular, interpretable foundation for adaptive spacecraft RPO.
