摘要: 应用单框架控制力矩陀螺系统 (SGCMG)是大型航天器姿控系统较为理想的选择 ,但是该系统存在严重的奇异现象 ,增加了操纵律的设计与开发的难度。文章从奇异性分析的角度对单框架控制力矩陀螺系统的奇异状态进行了研究 ,提出了奇异可回避性的判别方法 ,并据此对 SGCMG系统奇异状态进行了系统的分类 ,针对常用的各种构形的 SGCMG系统进行了讨论

关键词: 控制力矩陀螺, 框架结构, 奇异性分析, 研究

Abstract: Single Gimbal Control Moment Gyro (SGCMG) system is the best choose of large spacecraft attitude control system.But the phenomenon of singularity exists in this system,this increases difficulty in designing steering law.The singularity states of SGCMG system on the base of singularity analysis are studied.The criterion of singularity avoidance is proposed.According to this criterion,singularity states are classified per fectly.At the same time,singularity of SGCMG system at all kinds of frames is discussed in common.
