Abstract

Abstract: 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.
