摘　　要：针对制导炸弹对地垂直攻击的要求,研究了导弹攻击地面运动目标的弹目三维运动规律,构造了带有落角约束的导弹运动方程,并利用反步控制方法,研究了带落角约束的三维近垂直击顶新型末制导律。仿真结果表明,该新型制导律能够在目标机动的情况下满足近垂直击顶的要求,脱靶量也在允许的范围之内。Accounting for the requirements of the terminal angular constraint of the guided bomb,the law of three-dimensional motion law between missile and target is studied,the equation of missile motion with a angle constraint is constructed,the backstepping control theory is used to design a new three-dimensional guidance law which can nearly vertically strike the top of the target. Simulations results show that the new guidance law can meet the request of missile nearvertical strike on the top of the target,even if the target escapes in a great maneuver. The miss distance is also within the permitted range.
