Multiple-spacecraft clustering by piecewise linear quadratic control

Multiple-spacecraft clustering by piecewise linear quadratic control
複数の人工衛星が地球周回軌道の1部を囲む有界領域を航行させるためのニアミス回避・燃費低減・自動制御を満たす軌道誘導則は線形力学であるにもかかわらず未だ構成されていない。導出の指針を得るために、より単純化されたモデルである自由空間の1次元航行をする複数宇宙機において3条件を満たす協調制御を解析した。宇宙機が2機あるいは3機の場合に、2機のニアミスを消費燃料最小の自動制御で回避する誘導則を導いた。しかし、3機によるニアミス回避を低燃費で行なうことが証明されなかったため、大域的な探索をするために区分2次となるペナルティ関数による最適化を試みる指針を与える。 Fuel-minimum optimization of one-dimensional traffic by multiple-spacecraft
