超声速拦射导弹的一种预测变结构中制导律

针对攻击超声速大机动目标的超声速拦射导弹的中制导律设计问题,基于变结构控制理论并结合预测导引的思想提出一种预测变结构中制导律。该制导律能够零化导弹速度前置角,交班时过载较小,从而很好地满足中末交班要求。通过调节预测步长,在目标作大机动的情况下,既能保证中末交班时几乎为零的导弹速度前置角,又能有效地减小交班时导弹法向过载。最后在Matlab/Simulink环境下对攻击超声速蛇形机动目标进行了仿真,仿真结果表明了所设计的制导律的正确性和攻击超声速大机动目标的有效性。

Forecast Variable Structure Midcourse Guidance Law Design for Supersonic Intercept Missile

Based on the variable structure control theory and forecast guidance,a forecast midcourse guidance law is proposed for the supersonic intercept missile attacking supersonic and snakelike mobile targets in this paper.This guidance law can complete midcourse-terminal handover shift well,because it not only can get almost the zero missile velocity deflection angle,but also effectively minimize the normal overload at the time of handover.By using the Matlab/Simulink programming,simulation results were presented...
