For the attitude control problem of terminal approach phase of RVD, the feedback linear theory was adopted to linearize nonlinear attitude dynamics, and a phase-variable states space model was deduced. The terminal sliding mode control theory considering the disturbances was used on the basis of the deduced model. Furthermore, this paper introduces a controller which implements the attitude tracking and controls the states tracking errors convergent to zero in the finite time. For the example given, the control results satisfy the terminal time constrain and the tracking errors were convergent to zero, and this demonstrates that the controller is robust.
