以水中弹药对水面目标进行高效攻击为背景,提出了一种水中弹药垂直攻击目标的变结构导引方法,通过假设忽略目标的横滚与纵向的机动,假设目标在水平面内作匀速直线运动,同时假设弹体无横滚,建立了水中弹药运动学模型方程、动力学模型方程及变结构垂直导引与控制. 应用Matlab/Simulink软件搭建了数学仿真系统并对水中灵巧弹药变结构垂直导引进行了闭环系统仿真研究,结果表明,所提出的水中弹药变结构垂直导引攻击目标的设计方法能够适应垂直攻击目标的设计要求,与预期的指标要求吻合良好.

Variable Structure Vertical Guidance Law and Simulation of Underwater Ammunition

On the background of underwater ammunition attacking the water surface target effectively, a type of variable structure vertical guidance law and control method of underwater ammunition was proposed. By assuming that the target's rolling motion and longitudinal maneuvering were ignored, the movement of target was in a straight line with a constant speed in the horizontal plane and the smart underwater ammunition has no rolling motion, kinematics model equations, dynamic model equations and variable structure vertical guidance law and control of the underwater ammunition were established. Through the application of Matlab/Simulink software, the mathematical simulation system was built and the closed-loop system simulation of variable structure vertical guidance and control of the underwater ammunition was studied. The simulation results show that the proposed design methods of vertical guidance law and control can satisfy the design requirements of vertical attack target, and they are in good agreement with the standard expected.
