控制力矩陀螺系统奇异性仿真分析

Simulation Analysis on Singularity of Single-Gimbal Control Moment Gyros

对剪式控制力矩陀螺系统中单个陀螺失效的奇异性进行了研究.针对正交安装剪式控制力矩陀螺群中一个陀螺失效的情况,给出了剩余冗余控制力矩陀螺系统的奇异角动量超曲面仿真曲线,并对奇异面的构成和特点进行了分析,为此种构型下控制力矩陀螺群的操纵律设计提供了重要依据.

The singularity of the scissored pairs of control moment gyros （CMGs） system is researched in this paper, in which one singl one SGCMG is invalid in the o e - gimbal rthogonally control moment gyros （SGCMG） is invalid. For the situation that mounted scissored pairs of CMGs, the singular angular momentum hypersurface of residual SGCMG system is drawn and the composition and characteristics of the singular surface are analyzed, which would provide important basis for designing the steering law of SGCMG system.
