在引入鱼雷导引禁区和鱼雷有利导引点的基础上，用模糊逻辑理论，提出了一种能自动实现现在方位导引和无干扰导引的混合导引律。该导引律通过两组误差信号和多目标规则库，使得鱼雷可在无干扰导引法和现在方位导引法之间自由切换，避免了传统方法需要人工切换的缺陷，所设计出的模糊导引律不受制导站、鱼雷、目标自由运动的影响，而且可以连续地适应各种工作环境 Based on the introduction of the torpedo guidance forbidden zone and the torpedo favorable guidance point, a hybrid navigation law that can automatically realize the current azimuth guidance and the no-interference guidance is proposed based on the fuzzy logic theory. The guidance law through two sets of error signals and multi-objective rule base, making the torpedo can be switched between the interference-free guidance method and the current azimuth guidance method to avoid the shortcomings of the traditional method requires manual switching, the designed fuzzy Guidance law from the guidance station, torpedoes, free movement of the target impact, and can be continuously adapted to a variety of working environment
