摘　　要：针对反鱼雷鱼雷(anti-torpedo torpedo, ATT)拦截距离短、机动性要求高的特点,将最优控制和滑模控制相结合,设计了最优滑模导引律,保证拦截过程ATT需用过载相对较小且对于来袭鱼雷的机动具有一定的适应能力。针对ATT需要在短时间内快速调整姿态的问题,设计了ATT变指令周期控制方式,对ATT和来袭鱼雷的距离进行分段,不同的距离采用不同的指令周期,并利用蒙特卡洛法分析了变指令周期和固定指令周期控制下的ATT拦截弹道特性以及命中概率。仿真结果表明:变指令周期导引对于加速度很小或较大的来袭鱼雷均具有较高的拦截概率,且平均脱靶量较小;对于固定指令周期导引律,无论来袭鱼雷是否机动,均存在较大脱靶量。In view of the characteristics of short interception distance and high maneuverability requirement of anti-torpedo torpedo(ATT), an optimal sliding mode guidance law is designed by combining optimal control with sliding mode control, which ensures that the ATT in interception process needs relatively small overload and has certain adaptability to the maneuverability of incoming torpedoes. Aiming at the problem that ATT needs to adjust its attitude quickly in a short time, a variable instruction period control method of ATT is designed. The distance between ATT and incoming torpedo is segmented, and different instruction periods are used for different distances. Monte Carlo method is used to analyze the trajectory characteristics and hit probability of ATT Interception under the control of variable instruction period and fixed instruction period. The simulation results show that variable instruction period guidance has higher interception probability for incoming torpedoes with small or larger acceleration, and the average miss distance is smaller, whereas for the fixed instruction cycle guidance law, there is a large miss distance regardless of the maneuverability of the torpedo.
