| 摘 要： | 针对以往模糊建模方法中算法中算法过于复杂的问题，提出了一种简单而有交的复杂系统模糊建模新方法。该方法是基于输入空间的模糊划分，计算给定样本在各模糊子空间的隶属度，并列用卡尔曼滤波算法辨识模糊模型的结论参数。整个辨识过程与模糊聚类方法和误差反馈学习方法相比所需的CPU时间最短。最后通过著名的Box-Jenkins煤气炉数据仿真结果证明了该方法的有效性与实用性。 |

| Abstract: | In accordance with the problems that the algorithm is too complex in the past fuzzy modeling methods, this article proposes a new method of fuzzy modeling for complex system. The method is simple and powerful. This method is based on fuzzy partition of input space, and it calculates the grade of membership of given patterns in each fuzzy subspace with the consequence parameters identification obtained by using Kalman filtering algorithm. The whole identification process takes much less CPU time than the fuzzy clustering method and the error-feedback learning algorithm. Finally the effectiveness and practicability of this method is demonstrated by the simulation results of the famous Box-Jenkins gas furnace data. |
