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.

Abstract: 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 simulation results show that the precision of attitude control is about 0.3°, when the reaction wheel is installed with a certain angle from X axis in XZ plane. The control method is applicable for micro-satellite. 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.
