为了达到提高制导系统精度、降低过载的目的,该文在传统制导方法的基础上增加了对目标历史运动数据的分析,从而生成目标视线角的预测值,修正制导律。该文首先进行了制导系统相对运动方程的建立,然后推导了直接力/气动力符合控制下的制导规律,在此基础上引入基于目标视线角预测方法的制导律,最后对该方法进行仿真验证。仿真结果表明基于目标视线角预测方法的制导律可以达到提高精度、降低过载的效果。
In order to improve the accuracy of the guidance system and reduce the overload, this paper adds the analysis of the target historical movement data to the traditional guidance method to generate the predicted value of the target line-of-sight and correct the guidance law. Firstly, the paper establishes the relative motion equations of guidance system, and then derives the guidance law under direct force / aerodynamic compliance control. Based on this, the guidance law based on the target line-of-sight prediction method is introduced. Finally, the method is verified by simulation . The simulation results show that the guidance law based on the target line-of-sight prediction method can achieve the effect of improving the accuracy and reducing the overload.
