自导深弹导引弹道设计与仿真

针对自导深弹自导系统设计过程中,面临的简化目标探测系统和弹体姿态控制系统的要求,设计采用自动调整提前角导引算法作为自导策略;操极限舵,采用直接由导引算法得出舵角值的弹体姿态控制方法.给出了纵平面内深弹运动学模型、目标运动学模型、深弹与目标相对运动模型的数学描述,并在Matlab/Simulink 环境下完成了以上三个模型的实现和子模块封装, 编制了描述深弹整个自导过程的Simulink模块化程序;给出了自导深弹自动调整提前角导引方法的实现原理,并基于Simulink/StateFlow工具箱建立了该导引算法的图形化程序进行了仿真研究,验证了导引方法的有效性.

Trajectory Design and Simulation Research on a Model of Self-guided Depth Bomb

In the process of self-guided depth bomb's homing system design,be faced with the requirement of simplifying the target detect system and bomb attitude control system,self-correcting ahead angle arithmetic is adopted as homing strategy.The mathematic model of depth bomb's kinematics,target's kinematics and the relative motion is discussed,and the subsystem encapsulation of the three models is finished in Matlab/Simulink environment.A modularized modeling method for describing the entire acoustic homing proc...
