Study on Sampling Based Discrete Nie-Tan Algorithms for Computing the Centroids of General Type-2 Fuzzy Sets

open access: yesIEEE Access, 2019
General type-2 fuzzy logic systems (GT2 FLSs) have become a hot topic in current academic field. Computing the centroids of general type-2 fuzzy sets (also called type-reduction) is a central block in GT2 FLSs. Recent studies prove the continuous Nie-Tan

A robust type‐2 fuzzy logic‐based maximum power point tracking approach for thermoelectric generation systems

open access: yesInternational Journal of Energy Research, 2021
SummaryA robust type‐2 fuzzy logic (FL)‐based approach for maximum power point tracking (MPPT) is proposed in this work. The method is used to increase the energy efficiency of thermoelectric generators (TEGs). Type‐2 FL was applied to adapt the variable step size of incremental resistance (INR) MPPT to track the maximum available power of a TEG.

Review of Recent Type-2 Fuzzy Controller Applications

open access: yesAlgorithms, 2016
Type-2 fuzzy logic controllers (T2 FLC) can be viewed as an emerging class of intelligent controllers because of their abilities in handling uncertainties; in many cases, they have been shown to outperform their Type-1 counterparts. This paper presents a
