This paper focuses on the attitude tracking control of spacecraft. Firstly, the modified Rodrigues parameters are selected to characterize the spacecraft’s attitude, whose mathematical model is then established by considering the uncertainties of the spacecraft parameters and the bounded disturbances. The mathematical model of the spacecraft is transformed into a type of high-order fully actuated (HOFA) system with uncertainties. Then, based on the HOFA system approach, a robust controller for a type of HOFA system with uncertainties is designed, which can ensure that the system states converge to an arbitrary ellipsoidal region. Finally, the validness of the designed controller is verified by simulation.
