单兵火箭弹简易制导控制方法研究

为降低单兵制导火箭弹的成本,同时确保其具有较远的作用距离和较高的命中精度,针对静止目标,设计了单兵火箭弹简易制导控制律.首先,将飞行弹道进行分段设计,以瞄准线作为基准弹道,采用虚拟目标导引法实现对基准弹道的跟踪;然后,进行STr控制器的设计,基于典型设计点处控制器的参数插值,得到实时飞行过程中的控制器参数,确保火箭弹在整个飞行过程中具有较高的控制精度;最后,进行了仿真计算,通过仿真结果分析可知,所设计的制导控制系统具有较高的鲁棒性.

Research on simply guidance control method for individual rocket projectile

To reduce the cost of guided individual rocket projectile,and to ensure that it has a longer striking distance and higher accuracy,the simply guidance control law of the individual rocket projectile was designed aiming at the static target in this paper.First,the flight trajectory was segmented,aiming line was used as the standard trajectory,the standard trajectory tracking was realized by the virtual target guidance method.Then the STT controller was designed to get the controller parameters in real time flight based on the parameter interpolation of the controller at typical design points,so as to ensure the rocket has a higher control accuracy in the whole flight envelop.Last,the simulation analysis shows that the designed guidance control system has high robustness.
