摘　　要：为提高反鱼雷鱼雷的命中精度,采用变结构控制技术设计了反鱼雷鱼雷(ATT)导引律,通过控制ATT的航向角将ATT导向目标鱼雷,在理论上证明了该导引律能够将反鱼雷鱼雷精确导向目标,并在该导引律的基础上建立了ATT的拦截弹道的仿真模型。拦截弹道仿真表明,该导引律对目标机动具有很强的鲁棒性,能够精确打击机动目标,系统响应速度快,弹道稳定平滑,法向过载小。In order to improve hitting precision of anti-torpedo torpedo（ATT）,a guidance law for ATT based on variable structure control technology was put forward. ATT was guided to target by controlling the course angle of ATT. It was proved that ATT can hit target precisely by the new guidance law. Based on the guidance law,the simulation model of intercepting trajectory of ATT was built. The robustness of the guidance law to maneuver target is strong, and the maneuver target can be hit precisely. The response speed of system is fast,the trajectory is stable and smooth; the normal overload is small.
