A sufficient condition for null controllability of nonlinear control systems [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2009
Classical control methods such as Pontryagin Maximum Principle and Bang-Bang Principle and other methods are not usually useful for solving opti-mal control systems (OCS) specially optimal control of nonlinear systems (OCNS).

A measure of consistency for fuzzy logic theories

open access: yesMathematical Methods in the Applied Sciences, 2021
Fuzzy logic has shown to be a suitable framework to handle contradictions in which, unsurprisingly, the notion of inconsistency can be defined in different ways. This paper starts with a short survey of different ways to define the notion of inconsistency in fuzzy logic systems.

Prioritised fuzzy constraint satisfaction problems: axioms, instantiation and validation [PDF]

open access: yes, 2003
This paper identifies a generic axiom framework for prioritised fuzzy constraint satisfaction problems (PFCSPs), and proposes methods to instantiate it (i.e., to construct specific schemes which obey the generic axiom framework).

Similarity -Based Pattern Recognition for Disease Symptom Extraction and Characterization [PDF]

open access: yesNeutrosophic Sets and Systems
Neutrosophic Fuzzy Sets (NFS) expand upon classical fuzzy sets in the field of fuzzy set theory by including measures of truth, indeterminacy, and falsity.

A Theory for Measuring the Preference of Fuzzy Numbers

open access: yes2020 IEEE 20th International Symposium on Computational Intelligence and Informatics (CINTI), 2020
Here, sigmoid function-based preference measures for intervals and fuzzy numbers are introduced, and their main properties are outlined. Also, formulas for the numerical computation of the proposed preference measures are presented. Next, it is demonstrated that the proposed preference measures for intervals and fuzzy numbers are asymptotically the ...

On Intuitionistic Fuzzy Entropy of Order-α

open access: yesAdvances in Fuzzy Systems, 2014
Using the idea of Rènyi’s entropy, intuitionistic fuzzy entropy of order-α is proposed in the setting of intuitionistic fuzzy sets theory. This measure is a generalized version of fuzzy entropy of order-α proposed by Bhandari and Pal and intuitionistic ...

A random set and prototype theory interpretation of intuitionistic fuzzy sets [PDF]

open access: yes, 2010
An interpretation of intuitionistic fuzzy sets is proposed based on random set theory and prototype theory. The extension of fuzzy labels are modelled by lower and upper random set neighbourhoods, identifying those element of the universe within an ...

New Similarity Measures of Pythagorean Fuzzy Sets and Their Applications

open access: yesIEEE Access, 2019
Similarity measure, as a tool to measure the similarity degree between two objects, is an important research content in fuzzy set theory. Pythagorean fuzzy set, as a new extension of fuzzy set theory, has been widely used in various fields.

Distance Measures Based on Metric Information Matrix for Atanassov’s Intuitionistic Fuzzy Sets

open access: yesAxioms, 2023
The metric matrix theory is an important research object of metric measure geometry and it can be used to characterize the geometric structure of a set. For intuitionistic fuzzy sets (IFS), we defined metric information matrices (MIM) of IFS by using the
