The invention discloses a spacecraft formation 6DOF output feedback control method considering visibility constraints, belongs to the field of spacecraft formation control, and aims at solving the problems existing in existing spacecraft formation control. The method comprises the following steps: S1, establishing a kinetic equation of a tracking star relative space failure target spacecraft based on Lie group SE (3); s2, introducing a configuration error potential function to obtain a configuration error vector; s3, establishing a visibility constraint: constructing a view field constraint which ensures that the target moment is in the view field of the kth tracking star and an inter-satellite sight shielding avoidance constraint which is established based on the maximum observation cross section; s4, designing a potential function meeting visibility constraints; s5, establishing an auxiliary power system based on the Lie group SE (3); s6, constructing spacecraft formation 6DOF output feedback control law # imgabs0 # based on auxiliary power system
