宇宙機自動ドッキングシステムを対象としたモデルベース開発手法・フレームワークの構築

抄録

Spacecraft automatic docking systems need to achieve high level of reliability, robustness, and safety. On the other hand, it is difficult to realize comprehensive evaluation and verification only by ground test due to issues with reproducibility of actual operation condition in the space environment. Therefore, model-based development method and framework targeting the spacecraft automatic docking system to realize efficient and reasonable analysis and evaluation regarding feasibility and safety have been constructed in Japan Aerospace Exploration Agency. This model-based development framework consists of off-nominal scenario identification based on model-based systems engineering method from safety point of view and evaluation of dynamic behavior with multi-physics and system-level integrated modeling and numerical simulation.
