太阳翼驱动机构对卫星姿态扰动特性评估
Characteristics evaluation of satellite attitude disturbance caused by solar array drive assembly
摘要
Abstract
In order to study the satellite attitude disturbance characteristics caused by solar array drive assembly(SADA),satellite attitude dynamics model considering the rotation of the solar arrays driven by SADA was established.An experiment scheme was designed to measure kinematic characteristics of SADA on-load.Through the experiment,kinematic characteristic curve of SADA on-load was obtained,and kinematic transfer function of SADA on-load was acquired by fitting experimental data.SADA kinematic model was substituted into satellite attitude dynamics model for simulation,therefrom getting satellite attitude control indicators when considering SADA motion.Based on kinematic characteristics and installation mode of SADA,a disturbance suppression strategy that interleaved the phases of the two SADA drive signals by 180° was designed,which was verified effective on disturbance suppression caused by SADA motion.The strategy has good engineering application value.关键词
