宇宙機間の相対位置の制御について

抄録

Formation flight control of two spacecraft is considered in this paper. A trajectory of relative position change of one spacecraft with respect to the other is designed on the basis of the Hill's equation from the viewpoint of the minimum fuel consumption. The total fuel consumed along the trajectory is analytically obtained. Discrete two-degree-of-freedom control law is also proposed in order to realize the designed trajectory. The controller achieves deadbeat property of the closed loop system and guarantees the robustness to the controller gain decrease. Numerical studies are executed in order to verify the trajectory generation and the discrete control.
