摘要: 在对非合作航天器进行姿态接管控制时,可能面对目标航天器参数未知、构型改变引起的不确定性及目标施加的非合作控制输入等挑战。针对上述问题提出了一种基于预设性能控制理论的非合作航天器姿态接管控制方法。首先,建立了姿态跟踪运动的非奇异拉格朗日型模型;然后,利用跟踪微分器构造不包含角速度信息的广义状态量,设计无需参数辨识的非奇异预设性能控制器,并证明了系统状态变量的有界性和控制系统在预设的性能指标以内。最后,通过数值仿真验证了所提出方法的有效性及其对时变参数不确定性和非合作控制输入的鲁棒性。

Abstract: 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.

Key words: attitude takeover, non-cooperative spacecraft, prescribed performance control, estimation-free, nonsingular modeling
