| 摘 要： | 针对低高度、大倾角末端姿态约束问题,提出了一种弹道跟踪制导律.离线优化得到满足终端约束的基准弹道.为了避免出现奇异,将对位置的跟踪转换为对视线角及视线角速度的跟踪.根据当前状态,利用连续时间非线性预测控制,以弹道跟踪误差和控制能量的组合为性能指标,在线滚动优化得到制导指令,分析了制导律的参数选取,最后对该制导律进行了全...

| Abstract: | A guidance law with angle constraint was developed for an air-to-ground missile,which met the requirements of the low height and large impact angle.The reference trajectory was generated by the off-line optimizing.A continue predictive control law was designed to track the reference trajectory,it predicted trajectory by appropriate expansions,the optimal slide control was obtained through minimizing the predicted errors in the actual response,the desired response and current control expenditure.The trajecto... |
