In this paper, the adaptive attitude tracking control of spacecraft with unknown time-varying disturbances is studied. Firstly, the attitude model is established using modified Rodriguez parameters, which is transformed into a high-order fully actuated (HOFA) system model with unknown time-varying parameters. Then, a novel adaptive attitude tracking control strategy based on the HOFA system approach is proposed. With the proposed control strategy, the unknown time-varying disturbances are estimated and compensated. The system stability of spacecraft attitude is guaranteed via Lyapunov theory. Finally, the effectiveness of the proposed control strategy is verified through numerical simulations.
