主　　题：Adaptive control scheme Inertia estimation New combination Non-cooperative body attachment Robustness 

摘      要：When non-cooperative body attachment occurs in space, the inertia of the new combination and the change of the system s momentum are *** uncertainty may lead to the instability of the spacecraft s attitude *** order to solve this problem, we propose an adaptive control scheme based on the inertia estimation of the new, combined system of non-cooperative body and *** method can allow the new combination of different situations to reach a stable state with a high level of precision and *** this paper, the stability of the adaptive control scheme is proven by constructing a Lyapunov function.A simulation environment in which a non-cooperative body attaches to a satellite attaches to is *** simulation shows that the attitude error converges to a small field when using the control scheme, regardless of unfavorable cases, including unknown inertia parameters, added *** addition, the simulation results show the strong robustness of the control scheme for the new combination.
