摘　　要：以零化反导导弹的脱靶量为基础,利用变结构控制理论和非线性运动学方程推导出一种能够适应目标做大机动的滑模变结构制导律.建立了目标做螺旋机动的数学模型,通过末制导仿真验证滑模变结构制导律在拦截三维螺旋机动目标时具有响应快速性,视线角速率和脱靶量较小,对高速大机动目标具有很好的拦截效果.Variable structure guidance law is detruded which can be used for intercepting severity mobility target.It makes use of variable structure control theoretic and non-linear equation based on near zero-miss distance for ATBM.Mathematic model of target with gyroidal maneuver is built.The variable structure guidance law characterized by response celerity,little LOS angle speed and little miss distance is validated,and the guidance law can be used for intercepting high maneuver target very well.
