摘要
研究了制导炮弹最优滑翔弹道与控制问题.建立了滑翔弹道模型,以射程为指标函数,考虑终端速度、高度和弹道倾角约束,采用庞特里亚金极大值原理和共轭梯度法求出控制变量有约束的最优滑翔弹道,简要分析了滑翔增程机理.给出2种纵向通道控制结构,并进行控制参数设计,数值仿真表明2种控制结构均可实现对最优滑翔基准弹道的精确跟踪.
The optimal glide trajectory and control system of combined guidance munition were studied. Glide trajectory model was established. Taking range as the performance function, considering end velocity, height and trajectory slope angle constraints, the optimal glide trajectory was solved by maximum principle of Pontryagin and conjugate-gradient method. The control variable of trajectory is limited. The mechanism of extended range was analyzed briefly. Two control system frameworks of combined guidance munition and parameters were designed. The simulation result indicates that both the two control systems can track the nominal trajectory accurately.
