N2 - The finite-time attitude control problem for combined spacecraft with non-cooperative target is investigated in this paper. First, a novel dynamic model is developed using the interaction torque between the service and target spacecraft. Next, a super-twisting disturbance observer is improved to estimate the generalized disturbance for the service spacecraft in finite time. Then, a nonlinear terminal sliding mode attitude controller is designed for the combined spacecraft so as to converge the attitude system in finite time. Finally, numerical simulations validate the feasibility of the proposed controller.
