Interval type-2 fuzzy automata and Interval type-2 fuzzy grammar [PDF]
Journal of Applied Mathematics and Computing, 2021 The purpose of the present work is to introduce and study the concept of interval type-2 (IT2) fuzzy grammar which recognizes the given IT2 fuzzy languages. The relationship between IT2 fuzzy automata and IT2 fuzzy (weak) regular grammars is discussed.

IEEE Transactions on Fuzzy Systems, 2016 Type-2 fuzzy logic systems make use of type-2 fuzzy sets. To be able to deliver useful type-2 fuzzy logic applications we need to be able to perform meaningful operations on these sets. These operations should also be practically tractable. However, type-

Extending Similarity Measures of Interval Type-2 Fuzzy Sets to General Type-2 Fuzzy Sets [PDF]
2013 IEEE International Conference on Fuzzy Systems (FUZZ-IEEE), 2013 Similarity measures provide one of the core tools that enable reasoning about fuzzy sets. While many types of similarity measures exist for type-1 and interval type-2 fuzzy sets, there are very few similarity measures that enable the comparison of ...

Type-2 Fuzzy Entropy-Sets [PDF]
IEEE Transactions on Fuzzy Systems, 2017 The final goal of this study is to adapt the concept of fuzzy entropy of De Luca and Termini to deal with Type-2 Fuzzy Sets. We denote this concept Type-2 Fuzzy Entropy-Set.

The Construction of Type-2 Fuzzy Reasoning Relations for Type-2 Fuzzy Logic Systems
Journal of Applied Mathematics, 2014 Type-2 fuzzy reasoning relations are the type-2 fuzzy relations obtained from a group of type-2 fuzzy reasonings by using extended t-(co)norm, which are essential for implementing type-2 fuzzy logic systems.

Exploring Constrained Type-2 fuzzy sets [PDF]
2018 IEEE International Conference on Fuzzy Systems (FUZZ-IEEE), 2018 Fuzzy logic has been widely used to model human reasoning thanks to its inherent capability of handling uncertainty. In particular, the introduction of Type-2 fuzzy sets added the possibility of expressing uncertainty even on the definition of the ...

A Novel Technique for Load Frequency Control of Multi-Area Power Systems [PDF]
Energies, 2020 In this paper, an adaptive type-2 fuzzy controller is proposed to control the load frequency of a two-area power system based on descending gradient training and error back-propagation. The dynamics of the system are completely uncertain.

Adaptive Backstepping Fuzzy Control Based on Type-2 Fuzzy System [PDF]
Journal of Applied Mathematics, 2012 A novel indirect adaptive backstepping control approach based on type-2 fuzzy system is developed for a class of nonlinear systems. This approach adopts type-2 fuzzy system instead of type-1 fuzzy system to approximate the unknown functions.

Towards Interval Type-3 Intuitionistic Fuzzy Sets and Systems
Mathematics, 2022 In this work, several types of intuitionistic fuzzy sets, inspired by Type-2 and Type-3 concepts, are introduced. In particular, the newly proposed interval Type-3 intuitionistic sets are very interesting as they extend the opportunities of both interval
