Simulation on Attack Angle Motion for Controlled Projectile with Canard

In order to research dynamic process of the attack angle for controlled projectile under canard control,and seek the better control mode of the canard,taking the shell with a pair of canards for example,a 6-DOF(degree of freedom) rigid trajectory model with canard control is built to research the effect control progress of the attack angle.The control transfer function is deduced for predigesting analysis in feature points.The numerical calculation and simulation by MATLAB show that the maximal average force in period can not only improve manipulative efficiency but also lead to intensive swing of the angle.This is not suit for the shell demand with high stability.
