英文摘要：

Tethered space robot has a very bright future in the acquisition and operation for non-cooperative target.To solve the problem of large angle maneuver control under the interference of tether and the large angle measurement error,the complete maneuver model including the kinematic/dynamic model,the executing agency model and the interference model,was established in this paper.Under the guidance of the Lyapunov theory,the quaternion feedback controller was designed based on dynamic RBF neural network and adaptive control theory.The simulation shows that under the action of the control system,the maneuver is fast and the steady precision is ±3.5°,which can meet the needs of tethered space robot.It lays the foundation for precise operation of tethered space robot,which is the theoretical basis of our future on-orbit services.
