During the practical applications, the existence of measurement biases brings a great challenge to the attitude control design because they can lead to the mismatched disturbances in the spacecraft attitude kinematics. In this paper, an adaptive dynamic surface control (DSC) scheme is proposed for the attitude tracking of spacecraft under measurement biases. The inertia uncertainties, external disturbances, and actuator saturation are also included. A key idea of the proposed adaptive DSC scheme is that the adaptive updating laws are utilized in each step of the control design to estimate the mismatched and matched disturbances, respectively. The uniform ultimate boundedness of the whole closed-loop system is theoretically proved. Finally, the effectiveness and advantages of the proposed control scheme are verified through simulations and comparisons.
