N2 - For the spacecraft attitude system with external disturbance and system uncertainty in the task of non-cooperative target damping by electromagnetic eddy current, combining with the prescribed performance control theory, an adaptive sliding mode controller based on disturbance observer is designed in this paper. And this controller is designed to ensure the expected dynamic and steady-state responses of spacecraft attitude tracking control. A new finite time convergence performance function is designed, which doesn't need the exact initial error value. Aiming at the problem of control singularity caused by the increase of disturbance during steady-state of the new system after error transformation, we design an adaptive sliding mode controller based on disturbance observer, in which the observation gain matrix is related to the performance function. The effectiveness and robustness of the proposed control law is verified by simulation.
