潜射导弹水下运动过程仿真分析

为保证潜射导弹在不确定的海洋环境中能顺利出水,建立了潜射导弹水下及出水运动数学模型,对冷、热2种发射形式的导弹在无控、PID全程控制、模糊PID分段控制3种状态下的水下运动情况进行了仿真分析.结果表明,低海况下的海浪对导弹的出水姿态影响较小,高海况则不适宜进行导弹发射任务;在不确定的海况影响下,模糊PlD分段控制较PID全程控制更适合对导弹的出水姿态进行控制.

Simulation Analysis of Underwater Motion Process of Submarine Launched Missile

To ensure a submarine launched missile exceeding water successfully under uncertain ocean conditions,a mathematic model of submarine launched missile moving under or exceeding water,were established.The underwater motion of cold or hot launched missile with uncontrolled state,completely PID controlled state and segmented fuzzy-PID controlled state,were analyzed by simulation.The results show that the wave effect on the attitude of missiles exceeding water is small under relatively peaceful ocean states,inte...
