【摘要】：變速控制力矩陀螺(variable speed control moment gyro,VSCMG)簇相對于單框架控制力矩陀螺簇僅增加了飛輪轉(zhuǎn)速可調(diào)自由度,實現(xiàn)難度不大,但能夠緩解奇異問題�；诰�性代數(shù)理論,從機(jī)理上分析了已有的添加零運(yùn)動的加權(quán)偽逆操縱律不能規(guī)避VSCMG簇內(nèi)所有奇異點。針對添加零運(yùn)動的加權(quán)偽逆操縱律不能規(guī)避奇異點的問題,采用優(yōu)化方法,設(shè)計出一種新型的VSCMG簇操縱律,能夠規(guī)避采用傳統(tǒng)添加零運(yùn)動的加權(quán)偽逆操縱律不能規(guī)避的奇異點。最后搭建整個航天器姿態(tài)控制系統(tǒng),仿真驗證了所設(shè)計的新型操縱律奇異規(guī)避的有效性。
[Abstract]:The variable speed control moment gyroscope (variable speed control moment gyro,VSCMG) can only increase the freedom of the flywheel rotational speed in comparison with the single frame control torque gyroscope. It is not difficult to realize, but it can alleviate the singularity problem. Based on the theory of linear algebra, the existing weighted pseudo-inverse manipulation law with zero motion can not avoid all singular points in VSCMG cluster. In order to solve the problem that the weighted pseudo inverse manipulation law with zero motion can not avoid singularity points, a new VSCMG cluster manipulation law is designed by using optimization method, which can avoid the singular points that can not be evaded by traditional weighted pseudo inverse manipulation law with zero motion. Finally, the whole spacecraft attitude control system is built, and the effectiveness of the new control law is verified by simulation.
