摘要
针对在发射前预先装定弹道信息的传统弹道修正弹控制方法存在易受外界因素扰动的问题,提出了一种一维弹道修正弹自适应落点控制算法;通过建立弹道滤波模型外推弹道,利用自适应落点控制算法,得到阻尼器修正参数修正弹道,并根据弹丸飞行参数每隔特定时间循环上述过程实现自适应修正,直到引信引爆;仿真结果表明:滤波外推后的弹道更接近于实际弹道,经过多次弹道修正可以有效减小落点弹目偏差,与传统弹道修正方法相比较,改进弹道修正方法可较大幅度提高对静态目标的打击精度。
In view of the traditional trajectory correctional projectile loading trajectory intormahon before launch was easy to be disturbed by external factors, this paper put forward an one dimensional trajectory correctional projectile self-adaptive impact point control algorithm. Through establishing the ballistic filter model extrapolated trajectory and using the self-adaptive impact point control algorithm, we got the trajectory correctional parameters to modify the trajectory. Based on the flight parameters of the projectile, we cycled the above processes at a specified time to realize the self-adaptive correction until the fuse is detonated. Simulation results show that the trajectory after filter is more close to the actual trajectory, and it can reduce the impact of projectile target deviation effectively by several times of trajectory correction. Compared with the traditional trajectory correctional method, the improved trajectory correctional method has a greater improvement in the precision of the static target.
