  1. A novel dynamic evolutionary clustering algorithm ( deca ) is proposed in this paper to overcome the shortcomings of fuzzy modeling method based on general clustering algorithms that fuzzy rule number should be determined beforehand. deca searches for the optimal cluster number by using the improved genetic techniques to optimize string lengths of chromosomes ; at the same time, the convergence of clustering center parameters is expedited with the help of fuzzy c - means ( fcm ) algorithm. moreover, by introducing memory function and vaccine inoculation mechanism of immune system, at the same time, deca can converge to the optimal solution rapidly and stably. the proper fuzzy rule number and exact premise parameters are obtained simultaneously when using this efficient deca to identify fuzzy models. the effectiveness of the proposed fuzzy modeling method based on deca is demonstrated by simulation examples, and the accurate non - linear fuzzy models can be obtained when the method is applied to the thermal processes

    針對模糊演算法不適應復境的問題,提出了一種新的動態進化演算法,克服了傳統模糊建模演算法須事先確定規則數的缺陷.通過改進的遺傳策略來優化染色體長度,實現對個數進行全局尋優;利用fcm演算法加快中心參數的收斂;並引入免疫系統的記憶功能和疫苗接種機理,使演算法能快速穩定地收斂到最優解.利用這種高效的動態演算法辨識模糊模型,可同時得到合適的模糊規則數和準確的前提參數,將其應用於控制過程可獲得高精度的非線性模糊模型
  2.
