基于Simulink的简易控制单兵火箭弹弹道仿真

Trajectory Simulation of Single Solider Antitank Rocket Based on Simulink

单兵火箭弹的简易控制,将弹体动力学与运动学、气动力计算、简易姿态控制等模块连接建立了六自由度弹体运动数学模型,并在Matlab/Simulink环境下开发了由各模块组成的全弹道仿真数学模型。针对初始段扰动等问题,通过无控弹道与有控弹道的仿真分析比较,对初速较低的增程单兵火箭弹采用姿态修正可提高射程和精度。

A simply controlled single solider antitank rocket six-DoF motion mathematical model consists of body dynamics and kinematics block, aero dynamics block and simple attitude control block. Based on Matlab / Simulink, the whole trajectory simulation mathematical model is developed. Aimed at the initial disturbance, contrast the uncontrolled trajectory with controlled trajectory, the model can obtain the necessity of the trajectory correction for range enhanced antitank rocket with low initial velocity.
