战术导弹垂直发射快速转弯复合控制研究

摘要

战术导弹垂直发射的关键技术之一是实现快速转弯,研究了垂直发射快速转弯复合控制技术.针对空气舵/扰流片推力矢量复合控制技术,提出了战术导弹垂直发射初段程序转弯方案；建立了导弹的空气舵/扰流片推力矢量复合控制数学模型；通过设计线性组合的舵复合控制策略,将系统由多输入-单输出,转变为单入-单出系统,推导了复合控制弹体的传递函数,设计了复合控制回路,并利用频域分析方法进行了回路分析,纵向通道频域特性分析表明,系统具有良好的鲁棒性和动态品质；最后通过弹道的六自由度仿真,结果验证了所设计的复合控制策略的可行性.%One key technology of vertical launching tactical missile is to realize fast turn.This research aims to design an air vane/spoiler thrust vector compound control strategy to solve this problem.Based on the spoiler,a pitchover project was raised for the initial period of vertical launching tactical missile.A linear combined,compound strategy was devised,which transforms multi-input-single output system into single input-single output system.The missile body transfer function was established.The loop for compound control was designed then analysed with a frequency method.Frequency domain analysis for the longitudinal loop shows that the system has perfect robustness.The six-degree-of-freedom trajectory simulation is conducted to prove the feasibility of designed compound strategy.
