| 摘 要： | 为了研究模糊逻辑系统新的结构辨识方法, 提出采用基于山峰函数的减法聚类算法构造模糊逻辑系统的初始结构, 并利用奇异值分解(SVD)算法分析了模糊规则与奇异值、累积贡献率以及索引向量的关系, 从而实现了模糊逻辑结构的优化. 最后, 对该算法的可行性和有效性进行了仿真验证和性能比较, 取得了较好的效果. |

| Abstract: | Aimed to explore the new algorithms of structure identification for fuzzy logic systems, a substration clustering algorithm based on mountain functions to set up the initial fuzzy logic structure was used, and singular value decomposition (SVD) was adopted to analyze the relationships between fuzzy rules and singular values, cumulative contribution ratios, index vectors. Meanwhile, the optimized structure of fuzzy model was obtained. Finally, simulations and performance comparison show that the optimized algorithm was feasible and effective. |
| Keywords: | subtraction clustering singular value decomposition (SVD) fuzzy logic system structure identification |
