| 摘 要： | 发射角精度对于导弹飞行中的初始扰动会产生比较大的影响,发射角精度主要受随动系统的影响。首先对随动系统的输入信号进行了分析,讨论了目标等速等高直线飞行的情况,得出了输入信号变化的复杂性,从而得出讨论动态误差的必要性;然后对数字伺服控制系统进行了讨论,通过对单位反馈系统传递函数的分析,得到在一阶系统下的动态误差系数;最后根据典型目标的特性,仿真了动态误差的变化规律,研究了随动系统的动态误差对舰空导弹拦截目标的脱靶量影响。

| Abstract: | The lancher error may make an important influence between the flight of the ship-to-air missile.Guidance accuracy of ship-to-air is mainly influenced by servo system.Firstly,the input signal of servo system is analysed.According to discussing the target of constant high straight flight,the complexity of the input signal changes and the necessity of the dynamic error are gotten.Then the digital servo control system is discussed.The transfer function of unit feedback system is analysed and dynamic error coefficient of first-order system is gotten.At last,according to the feature of typical target,the orderliness of the dynamic error is simulated.The influence in the missdistance of the ship-to-air by dynamic error is also researched. |
