摘要
针对被动自导的超空泡航行体拦截近距离机动舰船目标问题,利用视线角变化率这一易获取信息,设计了一种有限时间收敛滑模末制导律。对制导律参数取值范围进行了分析,结合跟踪微分器对目标法向机动进行了状态重构。针对典型对抗态势进行了仿真与分析,结果表明该制导律可以在目标机动信息较少的情况下获得较好的攻击效果,目标加速度估计误差较小且快速收敛。
Aiming at the problem that passive self-guided supercavitating vehicle intercepting close-range maneuvering targets,a finite time convergent sliding mode terminal guidance law is designed by using the easily obtained information of the line-of-sight angular rate.The value ranges of the guidance law parameters are analyzed,and the target acceleration normal to the line-of-sight is estimated with the tracking-differentiator.The guidance law is simulated and analyzed under a typical engagement scenario,with the results showing that it can achieve ideal attack results using little information on target maneuvering.The estimation of target acceleration is accurate and converges rapidly.
