Fuzzy control with fuzzy inputs

IEEE Transactions on Fuzzy Systems, 2003
This paper is concerned with the use of fuzzy inputs in fuzzy logic controllers. A precise representation of fuzzy logic controllers by means of mappings is used to introduce different ways for dealing with fuzzy inputs. Two types of fuzzy inputs are presented and their potential use in fuzzy control is discussed.

Fuzzy contactibility and fuzzy variables

Fuzzy Sets and Systems, 1982
Abstract This paper gives some advanced developments of possibility measure theory. There are two problems being solved in this paper: 1. 1. What is the most essential property of the possibility measures? 2. 2. What is the measure extension theorem concering the possibility measures?

Fuzzy Fractals and Fuzzy Turbulence

IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2004
In this paper, we have defined and discussed fuzzy fractals from image generation point of view. We have also proposed a fuzzy system modeling of a two dimensional turbulence just as a chaotic occurrence of fuzzy vortices in a two dimensional dynamic fluid.

Fuzzy Coloring of Fuzzy Hypergraph

2006
Practical tasks of map coloring in case of objects groups’ allocation, not connected by any binary relation, come to the problem of coloring of graph [1]. This task is closely connected to the calculation of internal stable sets of graphs, calculation of chromatic number and a chromatic class of the graph.

On the fuzzy cardinality of a fuzzy set

International Journal of General Systems, 2006
We look at problem of determining the number of elements of a fuzzy set and its cardinality. It is noted that the simple adding of membership grades often does not lead to a satisfactory results. We investigate the use of a fuzzy subset of the non-negative integers to represent the cardinality of a fuzzy set. We prove a fundamental relationship between

Fuzzy inclusion and fuzzy equality of two fuzzy subsets, fuzzy operations for fuzzy subsets

Fuzzy Sets and Systems, 1983
In this paper we introduce a new definition of fuzzy inclusion and equality between fuzzy subsets. The main idea is that we evaluate a fuzzy equality not only by one value, as was done up to the present, but by two ones, i.e. by a pair of numbers from the closed unit interval.

Fuzzy Numbers and Fuzzy Arithmetic

2008
The arithmetical and topological structures of fuzzy numbers have been developed in the 1980s and this enabled to design the elements of fuzzy calculus (see [6, 7]); Dubois and Prade stated the exact analytical fuzzy mathematics and introduced the well-known LR model and the corresponding formulas for the fuzzy operations. For the basic concepts see, e.

Fuzzy Points and Fuzzy Prototypes

2002
There has been considerable interest in the nature of fuzzy points and in their relationship to crisp points. This paper describes a very general approach to the characterization of points which treats them as generalized maps from one object to another in a 2-categorical framework. It will be shown that fuzzy points are also amenable to this treatment,
