摘要
现代战争对防空火炮、车载雷达、激光对抗等防空武器装备的随动系统提出了较高的要求。为了实现对防空武器随动系统精确、稳定、快速控制,提高研制过程中随动系统的调参效率,该文以某型号防空武器的随动系统为研究对象,运用系统辨识理论及方法,设计扫频信号范围。并结合实测的随动系统相频和幅频特性,使用非线性最小二乘曲线拟合法,针对不同的频率特性进行分段拟合,得到相对精确的随动系统数学模型。结果表明,辨识出的传递函数符合理论推导出的数学模型,辨识方法具有实用性,契合度很高,对实际随动系统的调参过程具有指导意义。
Modern war puts forward high requirements for air defense artillery,vehicle radar,laser confrontation and other air defense weapons equipment.In order to achieve accurate,stable,and rapid control of the air defense weapon’s follow-up system,and to improve the tone efficiency of the follow-up system during the development process,this article uses the follow-up system of a certain type of air defense weapon as the research object.Scanning signal range is designed.Based on the frequent and frequency frequency characteristics of the measured follow-up system,the non-linear minimum two-multiplication curve is used to formulate legal,and the relatively accurate follow-up system mathematical model is obtained for different frequency characteristics.The results show that the identified transmission function conforms to the mathematical model derived from theoretical derivation.The identification method is practical and highly fit,which has guiding significance for the reference process of the actual follow-up system.
