摘要
给出了自寻的导弹制导回路模型,提出了二阶系统等效时间常数的估算方法。利用该方法对制导回路动力学系统进行等效时间常数的求解,最终得到制导回路五阶系统的等效一阶系统模型。通过等效前后制导回路系统的无量纲脱靶量仿真,验证了该等效时间常数估算方法的正确性。
The guidance system model of homing missile is presented. The estimation method of ap- proximate time constant in two-order system is proposed. Based on the method, the approximate time con- stant of guidance dynamic system is obtained with solutions, and the approximate one-order system model of the five-order guidance system is gained. By comparing the simulation results of the normalized miss distance between the two guidance systems, estimation method of approximate time constant is validated.
