 note = {地球周回軌道上で衛星の修理や組み立てを行う「軌道上サービス」は、近い将来必須の技術となると考えられる。本研究ではこのサービスに必要な技術の一環として、小型衛星によるターゲットの回収を扱う。その際テザーシステムを導入することにより、推薬節減などの効果を得ることができた。テザーを長く伸展させ軌道変換に用いる研究は多くなされているが、このような用途での利用を扱ったものは少ない。この際にテザーのモデル化が必要となるが、テザーの数学的モデルはいまだに確定的なものがなく、従来の研究では柔軟性や質量を無視して数値シミュレーションが行われてきた例も多い。今回は比較的記述が簡単で、かつ質量や柔軟性の効果を表せる離散質点モデルを導入し、制御の効果などを確認した。また本研究では、数値シミュレーションと同時に2次元精密定盤を用いた実証実験を行い、制御の効果とそのロバスト性を確認することができた。, On-orbit services such as repairing failed satellites and assembling space structures are expected to be important space missions in near future. Tethered Retriever is proposed as an agent of retrieving failed satellites or assembling parts. This Tethered Retriever, TR for short, is a small satellite tethered to the Service Satellite, which can repair parts or supply expendables to the satellites to be served (it is called the Target). The TR is released from the Service Satellite, flies toward the Target, captures it, and comes back to the Service Satellite. During the travel to the Target, the Service Satellite controls tension of the tether to decelerate the TR. And after capturing, the Service Satellite rolls up the tether to retrieve the TR and the target. By making use of tether in TR system, there can be benefit especially in the point that the fuel consumption will be much reduced. Besides, the TR will not be lost even when some critical failures occur in the TR due to the physical connection. In this paper, discussed is the collaborative control of tension of the Service Satellite and thruster of the TR, mainly in the approach phase to the Target. Performed are numerical simulations as well as experiments using air-bearing test bed. Through the results of this study, it was shown that the proposed control algorithm is stable and robust against various kinds of errors., 資料番号: AA0047897047},
