基于变结构控制的反鱼雷鱼雷导引律

反鱼雷鱼雷（ATT）作为现代海战中的重要反鱼雷武器越来越受到世界各国的重视，由于ATT攻击的目标是来袭鱼雷而不是舰艇，相比之下，ATT对付目标的尺寸小、机动性好，传统导引律已经无法满足ATT的要求。鉴于此，提出基于变结构控制的反鱼雷鱼雷导引律，该导引律以航向角作为控制量，降低了ATT发动机设计要求，所需模型参数少，并且模型参数能够自适应调整，理论推导和仿真表明：该导引律对模型参数及环境干扰具有很强的鲁棒性，弹道稳定平滑，具有较高的命中精度。

Anti-torpedo Torpedo Guidance Law Based on Variable Structure Control

Anti-torpedo Torpedo （ATT） become a hotspot of international regard for that ATT is important anti-torpedo weapon in naval battles. For that ATT＇s target is small and have good flexibility since ATT＇s target is torpedo not warship, traditional guidance law have cannot meet ATT ＂s demand. Herein the paper put forward a guidance law for ATT based on variable structure control. In the guidance law, yaw angle is adopted as controller that can reduce design complexity of engine and need few model parameters that even can accomplish self-adaptive adjust. The theoretical analysis and simulation results show that the guidance law have good robusty for model parameters and jam , high hitting precision and stable trajectory.
