| 摘 要： | 在三维球坐标系下建立了导弹与目标的相对运动模型,把目标加速度视为一类有界干扰,针对大机动目标提出了一种基于零化导弹与目标视线法向速度的三维变结构鲁棒自适应末制导律,并根据Lyapunov方法设计了参数自适应律.通过计算机数值仿真验证了导弹与目标的相对视线角速度最终趋向于零,验证了制导规律的正确性和有效性.

| Abstract: | Three-dimensional relative motion model of missile and target is established in three dimensional spherical coordinates,the maneuvering acceleration of target is regarded as a disturbance with boundary,3-D variable structure robust guidance law for homing missile based on zeroing normal speed of LOS(line-of-sight) is presented in intercepting the high maneuverable target,and the adaptive parameters of system are designed by using of Lyapunov method.Numerical simulation shows that the rates of LOS approach z... |
