Correction Control Time Optimized Design of Two-Dimensional Trajectory Correction Projectile Based on PPNGA

Abstract:
Aiming at the trajectory optimization of the two-dimensional trajectory correction projectile, the pseudo-parallel niche genetic algorithm (PPNGA) is applied to the mathematical model of the two-dimensional trajectory correction projectile external trajectory to improve the projectile correction ability and shooting accuracy by optimizing the correction control time. A seven-degree-of-freedom rigid body ballistic equation is established to simulate the external ballistic movement process of a two-dimensional trajectory correction projectile, after which PPNGA is used to optimize the control time of the two-dimensional trajectory correction projectile, and the optimal control time under known shooting conditions is obtained. The simulation results under different control times show that when the correction projectile is corrected using the control time obtained by the optimization, the projectile is closer to the target position, the shooting accuracy is higher, and the concentration of the correction projectile is better, by which the validity and feasibility of the optimization method are verified. The research results have certain engineering value and can provide references for actual engineering.
