摘要
阐述脉冲控制的建模原理,分析了脉冲控制机理。研究表明:姿态脉冲控制与气动控制类似,改变弹道的过载主要是由气动力产生的,受高度和速度的限制;轨道脉冲控制与气动控制有本质不同,直接产生过载,响应时间比气动控制至少小一个量级;姿态脉冲控制时在弹体频率处有180°的相位延迟,轨道脉冲控制有较小的相位延迟。
The modeling theory and pulse-control mechanism were expounded. The results show that attitude-pulse-control is similar to aerodynamic-force-control, Normal acceleration is provided by aerodynamic force, which is restricted by flight height and velocity; Orbit-pulse-control is very different in that it provides normal acceleration without delay, and response time is reduced by one order of magnitude; Attitude-pulse-control behaves 180° phase lag at natural frequency of the missile body, however, the phrase lag of orbit-pulse-control is very small.
