针对超空泡航行体机动能力差、探测手段有限等特点,提出了一种基于目标舰船尾流梯度信息的变结构制导律.通过激光探测机动目标的尾流信息,动态解算尾流梯度方向;采用滑模变结构理论设计制导律,实现对尾流梯度方向的精确跟踪,最终完成对目标舰船的精确打击.该方法利用目标尾流信息,避免对目标运动状态进行复杂估计计算,不仅降低了对机动能力的要求,同时大大减小能量消耗,提高了有效航程.仿真结果表明,系统响应迅速,可以实现快速精确的目标跟踪打击,且具有很强的鲁棒性和抗干扰性.
Aimed at the poor maneuverability and limited detection of supercavitary voyage, a variable structure guidance law based on wake wakes of target warship is proposed. By detecting the wake information of maneuvering targets by laser, the wake gradient The guidance law is designed by using the sliding mode variable structure theory to realize accurate tracking of the wake gradient direction and finally to accurately strike the target ship.This method uses the target wake information to avoid the complicated estimation calculation of the target movement state, Which not only reduces the requirements on maneuverability but also greatly reduces the energy consumption and improves the effective range.The simulation results show that the system can respond quickly and quickly and accurately to target tracking attacks and has strong robustness and anti-interference .
