摘要
基于零化反导导弹的脱靶量,用变结构控制理论和非线性运动学方程推导了一种能适应目标作大机动的滑模变结构制导律。设计了一种新颖的模糊逻辑控制器,通过嵌入专家经验,实现了导引律系数的智能改变,建立了目标作螺旋机动的数学模型。末制导仿真结果表明:智能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,对高速大机动目标有较好的拦截效果。
A variable structure guidance law using variable structure control theoretic and non-linear equation which could be used for intercepting severity mobility target was put forward based on near zero-miss distance of the antimissile missile in this paper.A novel fuzzy logic controller was designed.By embedded experience of experts into rules,the controller could adjust the coefficients in the guidance law.The mathematic model of target with gyroidal maneuver was given out.The simulation results of the terminal guidance showed that the variable structure guidance law had the characteristics of response celerity,little LOS angle speed and small miss distance,and the guidance law could be used for intercepting high maneuver target very well.
