摘　　要：论文针对传统比例微分控制方法在鱼雷进行较复杂运动时无法有效抑制横滚的问题,采用滑模模糊控制方法,根据舵机阶跃响应曲线,确定模糊控制器规则表,模糊控制器的每个规则都为一个滑模控制器,系统控制量由模糊控制器的输出确定,将模糊控制不依赖于系统模型和滑模控制鲁棒性强的特点综合起来。以国外某鱼雷为例,设计结构简单易于工程实现的一维五规则滑模模糊控制器,经仿真与比例微分控制对比证明:当流体动力系数存在干扰,鱼雷进行各种运动时,滑模模糊控制都能很好地抑制鱼雷的横滚,震颤很小,鲁棒性好。The classical proportional-derivative control method can not control transversr-rolling effectively when torpedo takes complex movement. The rules table of fuzzy controller is determined by open loop step response for maximal and minimal rudder. Each rule of fuzzy controller is a sliding controller. The system control function is determined by output of fuzzy controller. And thus combines the advantages of sliding mode control and fuzzy logic control. Taking a torpedo for example,its controller is designed by this method and is tested by computer imitation. The results show that when the liquid disturbances existing and torpedo takes different movements, the transversr-rolling can be well controlled by sliding mode fuzzy control. The system＇s chattering is alleviated and robustness is improved.
