Abstract:
In this paper, we introduce a new hybrid fuzzy clustering approach for Takagi-Sugeno (TS) fuzzy modeling based on a hybrid fuzzy clustering scheme. The method consists of a sequence of the steps aiming towards construct an optimal Takagi-Sugeno fuzzy model from sample data. First, we apply the modified mountain clustering algorithm to automatically determine the number of cluster and initial cluster center. Second, the initial input-output space fuzzy partition matrix is constructed by the initial cluster centers and then the improved Gustafson-Kessel clustering algorithm is utilized to result in an optimal input-output space fuzzy partition matrix. Finally, the Particle Swarm Optimization (PSO) algorithm is utilized to fine tune the system parameters. Compared with other fuzzy modeling methods, the introduced method has the advantages of simplicity, high accuracy and can be handled by an automatic procedure. Numerical examples are provided to illustrate the performance of the proposed approach.
