Reconfigurability Evaluation of VSCMG Based on Power Consumption Constraint

In this paper, a reconfigurability evaluation method for Variable Speed Control Moment Gyroscope (VSCMG) based on power consumption constraint is proposed. Based on the spacecraft attitude dynamics model and the VSCMGs system model, the spacecraft state space equation is established with the VSCMGs system fault factor vector. And then, by judging the controllability and power consumption performance of the system, a multiple composite reconfigurability evaluation method based on power consumption and reliability constraints is designed. Finally, the simulation analysis of whether the VSCMGs system has reconfiguration after failure is carried out, and the simulation results are in line with the actual situation, which verifies the correctness and effectiveness of the evaluation method.
