摘要
运用区间二型模糊集合(Interval type-2 fuzzy sets,IT2FSs)的扩展原理将常规的数值函数转化为对应的区间二型模糊函数,并给出了相应的词计算(Computing with words,CW)方法与算法,最后分析了严格单调情况下基于区间二型模糊集合的单输入单输出系统的语言动力系统(Linguistic dynamic systems,LDS)稳定性.
The paper converts conventional numerical functions to their interval type-2 fuzzy sets counterparts by using their extension principle, then presents the corresponding method and arithmetic of computing with words, and finally gives the linguistic dynamic stability of SISO systems under strictly monotone functions in interval type-2 fuzzy sets.
