To improve the impact accuracy and maneuvering penetration ability of reentry warhead, hybrid actuators with single gimbal control moment gyroscopes(SGCMGs) and moving masses are applied to produce the sufficient moment for attitude control during the whole reentry process. Taking into account the uncertainty of physical parameters and external environment disturbances, the adaptive attitude controller is designed based on the backstepping control method, which can implement adaptive compensation to the uncertainty of moment of inertia and inhibit the effects of the moment disturbances to the attitude control system effectively. Simulation results show that the adaptive backstepping controller has a good tracking performance, and the attitude control strategy is feasible.
