| 摘 要： | 为了获得滑翔增程制导炮弹的最优滑翔方案弹道,利用庞特里亚金极小值原理建立了制导炮弹在纵向平面内的最优滑翔飞行运动方程。研究了最优滑翔弹道的解法,并对制导炮弹滑翔飞行的最优控制参数进行了设计。结果表明,优化得到的升力控制系数能够保证该弹的飞行水平距离最远,且最优升力控制系数在1附近变化,并最终趋近1。

| Abstract: | In order to obtain the optimal glide trajectory for the glide range-extended guided projectile(GREGP),the optimization glide flight kinematic equations in the vertical plane are established using Pontryagin minimum principle.The solution of the optimization glide trajectory is studied.The optimal control coefficients for glide flight of the GREGP are designed.The results show that the optimal lift coefficient can ensure the maximum range for the GREGP.The optimal lift coefficient changes near 1 and tends to... |
