摘　　要：利用多变量频域控制理论,定性分析和定量研究了斜置尾翼滚转弹的转速对俯仰通道和偏航通道耦合度的影响.研究表明,弹体滚转产生的Magnus效应和陀螺效应是导致俯仰通道和偏航通道交联耦合的原因,二者对耦合度的影响都不能忽略;随着转速的增加,俯仰通道和偏航通道的耦合度呈指数形式上升;在弹体固有频率附近,俯仰运动和偏航运动耦合性最强;在某个工作频率下,Magnus效应和陀螺效应对耦合度的影响可相互抵消.Based on the multi-variable frequency theory, the effect of spinning rate of a wing-deflection rolling-missile on coupling degree between pitch motion and yaw motion was analyzed qualitatively and quantitatively. The result indicates that the effect is brought about by the Magnus moment and the gyro moment, and the effect can not be ignored; the coupling degree increases exponentially as the increase of spinning rate, the coupling degree reaches the maximum when the spinning rate is the same as the intrinsic frequency of the missile body; Magnus effect and gyro effect can be counteracted at certain spinning rate.
