To increase the control accuracy and maneuver capability of the reentry vehicle, the composite actuators with Single Gimbal Control Moment Gyroscope (SGCMG) and Moving Mass(MM) are proposed to generate desired control torques for attitude control during the whole reentry process. The effect of SGCMGs and MMs on the moment parameter of inertia is analyzed. Considering uncertainty of the moment of inertia and highly nonlinear of reentry vehicle dynamics, an adaptive attitude controller is designed based on backstepping method. A control allocation strategy is also proposed for composite actuators. Simulation results demonstrate that the composite actuators can satisfy the torque demand during reentry process, the tracking of attitude angles has a good performance.
