AN EXTENSION-PRINCIPLE-BASED FUZZY MODEL AND ITS IDENTIFICATION ALGORITHM
Yixin Chen · 1999
An extended TSK model——ETSK model,based on LR type fuzzy numbers and their extended operations,is proposed in this paper.The input\|output analytic expression is proved and a parameter identification algorithm is also constructed to identify the areas and gravity centers of the membership functions of LR type fuzzy numbers.A kind of variable weight TSK model which is equivalent to the ETSK model is also deduced.Simulation shows that the ETSK model can give out more accurate long\|range predictions than an LM model and a TSK model.
