为满足单兵火箭弹道修正要求,采用了一种可依据指令系数自动转换的脉冲调宽/乒乓式混合控制方式。弹道仿真结果表明,在平缓弹道主要为脉冲调宽控制,能够达到较高的位置控制精度;在弯曲弹道主要为乒乓式控制,有利于提供较大的法向过载。可得如下结论:该控制方式能够满足单兵火箭弹道修正要求,对弹丸姿态变化没有明显影响;通过进一步改进两种控制的转换方式可以获得更好的控制效果。

The trajectory correction of shoulder-launched rocket is controlled by a mix way of pulse width modulation and Ping-Pang control method selected by control parameter automatically. The results of trajectory simulation show when it flies in smooth trajectory, it uses pulse width modulation method to improve position control precision; when it flies in steep trajectory, it uses Ping-Pang control method to improve normal direction overload. This control method can meet the need of trajectory correction. It seldom effect on rocket attitude. In the future, trajectory correction effect will be better by switching the two control methods more reasonably.
