远程弹道导弹闭路制导方法建模与仿真

Modeling and Simulation of Closed-loop Guidance Method of Long Range's Ballistic Missile

在文献[1]的基础上提出了建立虚拟目标点矩阵来计算需要速度的方法,简化了需要速度计算模型,推导了速度倾角计算公式,采用改变速度倾角来改变需要速度的方式,对导弹进行调姿以达到能量管理的目的,在此基础上分别建立了主动段和末修段闭路制导模型,并通过仿真计算验证该模型是正确的。

Based on literature[1]. a method of calculating the required velocity by setting up matrix of dummy aim is put forward, so that the model of calculating the required velocity is predigested, the formulation of the velocity obliquity calculating is presented, and the purpose of adjusting stance of missile to manage energy of the missile by the way of changing the velocity obliquity to change the required velocity is achieved. Based on these, the close-loop models of the boost phase and the revise phase are both set up. and lastly, the simulation shows that these models are correct.
