针对应用在固定翼双旋弹上的一种周期平均控制方法，通过对弹体修正组件滚转角进行傅里叶变换，得到了双旋弹在周期平均控制下角运动方程的模型，进而分析了周期平均控制下固定翼双旋弹的角运动响应，并根据双旋弹角运动特性和执行机构的性能限制给出了周期平均控制角频率的设计方法。引进2种具体的周期平均控制方案作为分析对象，并通过六自由度弹道仿真进行了验证。结果表明，对固定翼双旋弹角运动响应的分析能够反映周期平均控制的特性，周期平均控制角频率的设计方法可以设计出合理的角频率。
To study the period average control method applied to the dual-spin projectile with fixed-canards, the Fourier transform of the roll angle of the course correction fuse is used to obtain the angular motion model for the dual-spin projectile under period average control. Then the angular motion of the dual-spin projectile with fixed-canards under period average control is analyzed. A design of the angular frequency of the period average control is proposed based on the performance of the angular motion and the performance limitations of the actuator. Two specific designs are analyzed and verified through six degrees of freedom simulations. The results indicate that the analyses of the angular motion of the dual-spin projectile with fixed-canards can reveal the properties of the period average control method, and the designed method can produce proper angular frequencies.
