In this article, we revisit the classical problem of attitude stabilisation for a rigid spacecraft with external disturbances. A global set stabilisation method using finite-time control technique is proposed. In the absence of disturbances, the states of the closed loop system will be stabilised in finite time to a set consisting of two equilibria. In the presence of disturbances, the states will be stabilised to a neighbourhood of this set. By constructing a particular Lyapunov function, it is proved that the closed-loop system satisfies global set stability. The control method in this article is based on set control idea and thus is more natural and energy-efficient. Numerical simulation results show the effectiveness of the method.
