摘　　要：针对常规航空炸弹制导化改进的作战需求,研究了制导控制系统采用稳定控制回路和弹体构成的闭环系统方案,提出了稳定控制回路的设计方法。首先,分析了影响制导化改进的常规航空炸弹命中精度的主要误差表现形式和分布规律模型。其次,给出了基于蒙特卡罗法的命中精度分析方法。最后,采用A、B两组试验仿真分析了落点分布规律对圆概率误差(circular error probability,CEP)值和命中精度的影响。结果表明,分析方法科学合理,控制系统的设计方案可行。To satisfy the operational requirement of guidance improvement for conventional aerial bombs,the scheme of a closed-loop system for the guidance and control system utilizing the stable control loop and projectile is studied,and the design idea of the stability control loop is put forward.Firstly,the representation of the main errors and the model of distribution are analyzed which impacts the hit accuracy of the guidance improved conventional bomb.Secondly,the analytical method of hit accuracy based on Monte Carlo is given.Finally,A and B two set of experiments are used to analyze the influence of the distribution rule of drop point on the circular error probability(CEP)and hit accuracy.The simulation results show that the analysis method is scientific and reasonable,and the design scheme of the control system is feasible.
