The Effect of Phase Difference of Linear Signal and the Control Signal on the Periodical Mean Force

The method of single channel control is often used in spinning missile.It expatiated on the causation of the periodical mean force,and gave the specific ways to get the direction and the magnitude of the force.The current linear method for controlling the spinning missile was also described.By analyzing the effect of phase difference between the linear signal and the control signal on the periodical mean force,it is concluded that the magnitude and the direction of the periodical mean force are both affected by the phase difference,and the period is π,further more,it gives out the precise changing rule,the maximum bias angle of the periodical mean force is 8.8°,and the maximum amplitude of the period mean force is 3 times of the zero phase difference condition.The conclusions are the important theoretical basis for the reasonable control of missile.
