摘要
为了提高飞轮控制可靠性,针对仅一个飞轮的非偏置动量三轴稳定控制问题,提出了飞轮不同安装方式下基于单飞轮和磁力矩器的稳定控制算法.仿真试验结果表明单个飞轮在XZ平面斜装时控制精度在0.3°左右,适合在纳星、皮星等微小卫星上应用,飞轮正装时仍可粗精度对地定向,适合多个飞轮故障情况下应用.
In order to improve the reliability of attitude control with reaction wheel, a control law is put forward, which is based on one reaction wheel and three magnetorquers in different fixing mode. The sim- ulation results show that the precision of attitude control is about 0.3 °, when the reaction wheel is in- stalled with a certain angle from X axis in XZ plane. The control method is applicable for micro-satelfite. When the wheel is installed along the roll or yaw axis, the satellite attitude can still be controlled. The control method can be used to a sick satellite.
