非合作航天器姿态接管无辨识预设性能控制

The control of attitude takeover for non-cooperative spacecraft faces challenges of the unknown dynamics, spacecraft reconfiguration and non-cooperative attitude maneuvering. An attitude takeover control method based on prescribed performance control theory is presented for non-cooperative spacecraft. Firstly, a nonsingular Lagrangian model for attitude tracking is constructed. Then, using the tracking differentiator, an extended state without the information of angular velocity is proposed and an estimation-free, nonsingular, and prescribed performance controller of attitude takeover is designed, proving the boundedness of the system states and the stability of the system. Finally, two groups of numerical simulations are organized to validate the effectiveness of the proposed method and the robustness against the uncertainties of time-varying parameter and the inputs of non-cooperative attitude control.
