Summary:The reconfigurability metric of distributed control torque gyro (CMG) of Jilin-1 super agile satellite is studied, and a reconfigurability metric of CMG under energy constraints is proposed in this paper. According to the design requirements for the attitude control system of Jilin-1 super agile satellite, the linear attitude dynamics and kinematic equations expressed in the form of state space are established, and the Gram matrix reconfigurability measurement scheme is designed. The minimum eigenvalue of the Gram matrix is used as a criterion for evaluating the reconfigurability of CMG. Finally, a reconfigurable simulation experiment is performed on the distributed CMGs, and the simulation results verify the validity of the metric, which will provide reference that research on the reconstruction and reuse of the actuator of the Jilin-1 super agile satellite.
