摘要
为了在弹道末段对弹道偏差实施修正,建立了脉冲控制力下的六自由度弹道模型,研究了单个脉冲修正能力的快速估算方法,并由落点弹道偏差量确定脉冲方向角和点火数,由此提出一种较为精确的修正方法。利用上述模型和算法,进行了仿真计算。仿真结果表明:脉冲控制可有效地修正弹道偏差,对算例中给定的目标偏差量,纵向修正误差约为10%,侧向修正误差约为5%。
In order to make the terminal correction projectile attack the target accurately,the 6-DOF equations for trajectory under impulse control were deduced.The threshold value,for the individual lateral pulse jet firing logic,was analyzed.The direction of impulse force and impulse number acting on projectile was confirmed by the information of trajectory and target.By means of the azimuth and algorithm above,a simulation was carried out.The results indicate that the impulse control can correct the range error effectively,and that this algorithm is suited for force control.The target deviation is corrected to about 10% in long direction,and 5% in side direction.
