摘　　要：提出了一种滚动-偏航平面两自由度偏置动量控制方法。在分析某通信卫星平台所受的环境干扰力矩对姿态扰动的基础上,依据Y轴偏置动量大小的影响、构型的角动量包络、动量轮最大角动量变化值和可靠性等参数,与现有的四轮金字塔构型两自由度偏置动量控制进行了比较,其性能更优越。A 2-Degree-of-Freedom （DOF） control wheel configuration in the roll/yaw plane is presented for the satellite attitude control. On the basis of analysis of environmental disturbance torques to some communications satellite platform, the wheel configuration is compared with the existing four-wheel pyramidal configuration according to parameters such as effect of biased momentum magnitude, storage capability, maximum momentum variation, reliability. It is concluded that the proposed configuration exceeds the four-wheel pyramidal configuration in performances.
