Stabilization of unknown nonlinear systems with T-S fuzzy model and dynamic delay partition

Journal of Intelligent & Fuzzy Systems, 2018
In this paper, a new method, namely, the dynamic delay partitioning method, is firstly developed to solve the problems of stability analysis and stabilization for a class of unknown nonlinear systems.

Fuzzy congruences and compatible fuzzy partitions

Fuzzy Sets and Systems, 1989
A natural concept of universal fuzzy algebra is introduced and it is proved that for a fuzzy congruence or a fuzzy partition to be compatible with a fuzzy universal algebra it is necessary and sufficient that level- wise compatibility is to be achieved.

Construction of Fuzzy Classes by Fuzzy Partitioning

2001
In this paper, we propose a new algorithm to infer automatically a fuzzy partition for the universe of a set of fuzzy values, when each of these values is associated with a class. This algorithm can be used in a fuzzy decision tree system to extract knowledge from a database and to construct a set of fuzzy rules.

Fuzzy Partitioning Methods

2001
In this chapter, we propose two new algorithms to infer automatically a fuzzy partition for the universe of a set of values, when each of these values is associated with a class. These algorithms are based on the use of mathematical morphology operators that are used to filter the given set of values and highlight kernel for fuzzy subsets.

Fuzzy δ–ε-partitions

Information Sciences, 2003
In this paper, the concept of a fuzzy δ-e-partitions of any fuzzy subset of the universe Ω is introduced as a generalization of that of a classical partition. The approach is based on four observations: the first one is that for any two members of a classical partition, their intersection is the empty set if they are not equal; the second one is that ...

Applying I-Fuzzy Partitions to Represent Sets of Fuzzy Partitions

2010
I-fuzzy partitions have been defined to represent uncertainty on the clustering process. They are based on interval type-2 fuzzy sets, also known as Atanassov's intuitionistic fuzzy sets.

Coarsening of fuzzy partitions

2015 IEEE 13th International Symposium on Intelligent Systems and Informatics (SISY), 2015
A vague partition U of a finite universal set X into c clusters, where each cluster is described by a fuzzy set on X, is considered. The concept of p-level sets [3] of fuzzy sets is extended to p-level matrices of fuzzy partitions. A method of gradual coarsening of U based on a sequence of p-level matrices derived from the membership grades of clusters
