摘　　要：For the challenging problem that a spacecraft approaches a tumbling target with non-cooperative maneuver,an anti-saturated proximity control method is proposed in this paper.First,a brand-new appointed-time convergent performance function is developed via exploring Bézier curve to quantitatively characterize the transient and steady-state behaviors of the pose tracking error system.The major advantage of the proposed function is that the actuator saturation phenomenon at the beginning can be effectively reduced.Then,an anti-saturated pose tracking controller is devised along with an adaptive saturation compensator.Wherein,the finite-time stability of both the pose and its velocity error signals are guaranteed simultaneously in the presence of actuator saturation.Finally,2 groups of illustrative examples are organized and verify that the close-range proximity is effectively realized even with unknown target maneuver.
