从奇异性分析角度对单框架控制力矩陀螺(SGCMG)的五棱锥构型(FPC)及其失效情况进行了研究。分别对1只陀螺失效及2只陀螺失效可能产生的各种构型进行了分析,给出了相应的奇异点角动量图并对几种重构后的构型评价指标进行计算和对比,更加深入地理解FPC构型及其失效重构后的性能。该文研究结果可为失效模式下的操纵律设计提供参考。此外,当FPC构型中有陀螺作为备份时,该文研究结果也为备份的选择提供了依据。
The pentagonal pyramid configuration (FPC) of single-frame controlled moment gyroscope (SGCMG) and its failure are studied from the perspective of singularity analysis. The possible configurations of one gyro failure and two gyro failures are respectively analyzed. The corresponding singular point angular momentum diagrams are given, and several reconstruction evaluation indexes are calculated and compared. In-depth understanding of FPC configuration and failure reconstruction performance. The results of this paper can provide references for design of manipulative law in failure mode. In addition, when the gyroscope is used as the backup in the FPC configuration, the results of this paper also provide the basis for the choice of backup.
