摘　　要：针对微小型弹药受终端角度约束和视角约束的制导问题,在二维平面内建立了微小型弹药与目标的相对运动模型,利用最优控制理论,将具有终端角度约束的制导问题转化为含终端约束条件的最优控制问题,提出了一种不需要视线角速率信息且满足终端角度约束的视角制导律,对视角制导律进行仿真研究。结果表明,当视角和可用过载足够大时,微小型弹药可以精确地命中固定目标,且终端角可以达到期望值。In order to solve the problem of impact angle constraint and field of view limit for the miniature ammunition guidance,the two-dimensional motion modeling for the miniature ammunition and target relative motion is completed,the optimal control theory is used,the problem of guidance with terminal angle constraint was transformed into the optimal control problem containing terminal constraint conditions,a look angle guidance law with terminal constraint which don＇t need the line of sight angle is presented,the feasibility of the guidance law is verified by the trajectory simulation. The results show that if the look angle and available overload are big enough,the miniature ammunition could accurately hit the fixed target and the impact angle could reach the expected value.
