摘　　要：推导了离轴三反(TMA)相机在轨成像的偏流角计算公式,并根据推导过程给出了偏流角的闭环和开环两种控制方式。分析了转序定义对控制的影响,获得了最佳转序。The formula for calculating the deviant angle of TMA camera was deduced in this paper. And the two kinds of control ways for deviant angle which were closed and open loop were given out. The effect of the rotating order on the control was analyzed. The optimal rotating order was acquired.

关 键 词：偏流角 像移速度 坐标系 转序
