This work addresses the problem of formation control for multiple spacecraft in a Planetary Orbital Environment (POE). Due to the diverse interferences and uncertainties in outer space, traditional control methods encounter great difficulties in this area. A new control approach inspired by human memory system is proposed, which is shown to be capable of learning from past control experience and current behavior to improve its performance and demands much less system dynamic information as compared with traditional controls. Both theoretical analysis and computer simulation verify its effectiveness.
