A guidance control method is proposed for the mission of autonomous rendezvous and docking with non-cooperative target spacecraft. Firstly, the relative motion equations of state are described in a line of sight coordinate frame. Then artificial potential function guidance based-fuzzy logic system, which adapts the parameters of the potential function, is used for chaser to approach non-cooperative target and avoid dynamic obstacles. Stability of the proposed method is analyzed by Lyapunov theory. Results obtained from numerical simulation studies demonstrate the validity of the method formulated in this paper.
