根据天宫一号目标飞行器的特点及交会对接任务需求,天宫一号目标飞行器选择单框架控制力矩陀螺作为姿态控制执行机构,这是控制力矩陀螺首次在国内航天器上应用.阐述了单框架控制力矩陀螺在天宫一号目标飞行器姿态控制上的应用,主要包括四个方面:构形选择、操纵律设计、角动量卸载、故障诊断与重构.天宫一号目标飞行器控制力矩陀螺系统采用五棱锥构形,其操纵律设计为带零运动的伪逆操纵律,控制力矩陀螺系统具备故障诊断和重构功能.
According to the characteristics of Tiangong-1 target vehicle and the demand of rendezvous and docking mission, Tiangong-1 target aircraft chooses single-frame control moment gyroscope as the attitude control actuator, which is the first application of control moment gyroscope in domestic spacecraft. The application of gyroscope in the attitude control of Tiangong-1 target aircraft mainly includes four aspects: configuration selection, manipulative design, angular momentum unloading, fault diagnosis and reconstruction. The control system of gyroscope on Tiangong-1 target aircraft uses a pentagonal pyramid structure The control law is designed to be a pseudo-inverse manipulative law with zero motion, and the control moment gyroscope system has the functions of fault diagnosis and reconstruction.
