A novel set of hybrid actuators with single control moment gyoscopes(SGCMGs) and moving masses are proposed to control a reentry warhead attitude, Since the hybrid actuators are both mounted inside the warhead directly, the ablation of them can be prevented and the aerodynamic shape can be preserved. Considering of the nonlinear and strong coupling characteristic of the reentry warhead dynamic model,...
In order to improve the impact accuracy and ability of the mobile penetration of reentry warhead, hybrid actuators with moving masses(MMs) and single gimbal control moment gyoscopes(SGCMGs) are used to produce enough torque for attitude control during the whole reentry process. Based on analysis of the torque generation mechanism of MMs and SGCMGs, a control allocation law is designed for the hybrid...
