-
摘要: 在深入分析线导+尾流自导鱼雷方位导引和前置点导引方法的基础上，综合方位导引和前置点导引的优点，给出了一种线导鱼雷的组合导引方法。通过引入模糊控制方法,根据目标运动状态和距离远近等信息自适应地调节导引参数，可有效地将鱼雷导引到尾流制导的理想攻击阵位上。仿真结果表明，该方法可以导引鱼雷按照要求入射目标尾流，且具有较好的弹道特性。该智能组合导引律结构简单，易于实现，有一定的工程实践意义。Abstract: Combining the advantages of azimuth guidance method and predicted point guidance method, an integrated guidance method for wire-guidance torpedo is presented. By introducing fuzzy control, the parameters of the integrated guidance method can be adaptively adjusted according to the information of target movement and the distance between torpedo and target. Thus the torpedo can be effectively guided to the position with ideal entering distance and angle for wake homing. Simulation results show the method can guide torpedo to the target wake with required entering angle and good trajectory .
