Abstract :
In this paper, we consider the motion control of spacecraft in the vicinity of the peanut-shaped asteroid. The implicit control concept is studied and orbital maintenance strategy to observe the peanut-shaped asteroid where the model of the gravity field is difficult to obtain is proposed. The implicit control law is characterized in terms of inverse problem of optimal control.
