摘　　要：研究反鱼雷鱼雷(anti-torpedo torpedo,ATT)与目标鱼雷纵向运动关系,推导ATT与目标鱼雷视线高低角状态方程,采用变结构控制方法设计控制器,将ATT与目标鱼雷视线高低角控制在零角度,通过Lyapunov稳定性理论证明了视线高低角能够控制在零角度.仿真分析表明,在所设计的变结构拦截导引律作用下,ATT与目标鱼雷在纵向的视线高低角稳定趋于零,ATT在纵向可精确命中目标.A state equation of the sight elevation angle between an anti-torpedo torpedo （ ATT） and a target torpedo is deducted according to the moving relation between the ATT and the target torpedo. Based on the state equation,a variable structure controller is designed to ensure that the sight elevation angle between the ATT and the target torpe-do is zero, which can be proved by Lyapunov stability theory. Simulation analyses show that the sight elevation angle between the ATT and the target torpedo converges to zero stably and the ATT hits the target precisely by taking the advantage of the longitudinal intercepting guidance law generated by the proposed variable structure controller.
