The main feature of one-shot thrusters is discreteness in both time and space domain. We apply discrete-time sliding mode control to the attitude control of a spinning vehicle. And we consider the space discreteness by applying a simple selection algorithm (SSA) to the selection of the combination of one-shot thrusters prearranged on the vehicle in order to generate the control force. SSA is the new algorithm we proposed, and its calculation load is light in computation load. We adopt a regulator scheme to reject disturbances of precession for precession for a LUNAR-A type penetrator , and conduct numerical simulations of the problem to show the effectiveness of the proposed control algorithm for one-shot thrusters.
