Fuzzy control and its application to a pH process [PDF]

In the chemical industry, the control of pH is a well-known problem that presents difficulties due to the large variations in its process dynamics and the static nonlinearity between pH and concentration. pH control requires the application of advanced

Four-quadrant Mine Converter Based on Fuzzy-PID Controller

Kongzhi Yu Xinxi Jishu, 2011
In order to realize four-quadrant mine converter with 1 140 V, the diode rectifier is replaced by the voltage source PWM rectifier ( VSR ) with double closed-loop arithmetic based on the Fuzzy-PID. Var analyzing VSR model which is established in Simulink

Dombi aggregation operator in terms of complex bipolar fuzzy sets with application in decision making problems

Complex & Intelligent Systems
The complex bipolar fuzzy sets fundamentally expand upon bipolar fuzzy sets and complex fuzzy set, and demonstrate efficacy in dealing with two-dimensional uncertainty, specifically where amplitude and phase information are both relevant.

Spectral Learning With Type-2 Fuzzy Numbers for Question/Answering System

, 2009
Graph-based semi-supervised learning has recently emerged as a promising approach to data-sparse learning problems in natural language processing. They rely on graphs that jointly represent each data point.

A New Method for Solving General Dual Fuzzy Linear Systems

Journal of Mathematical Extension, 2013
. According to fuzzy arithmetic, general dual fuzzy linear system (GDFLS) cannot be replaced by a fuzzy linear system (FLS). In this paper, we use new notation of fuzzy numbers and convert a GDFLS to two linear systems in crisp case, then we discuss ...

On Product of Positive L-R Fuzzy Numbers and its Application to Multi-period Portfolio Selection Problems

, 2020
With the wide applications of fuzzy theory in optimization, fuzzy arithmetic attracts great attention due to its inevitability in solution process. However, the complexity of the Zadeh extension principle significantly reduces the practicability of fuzzy

A Novel Approach to the Vectorial Redefinition of Ordered Fuzzy Numbers for Improved Arithmetic and Directional Representation

Applied Sciences
This paper presents a novel formulation of Ordered Fuzzy Numbers (OFNs), referred to as Vectorial Ordered Fuzzy Numbers (vOFNs). In contrast to the traditional definition based on a pair of functions, the vOFN framework employs a pair of vectors ...

A Method for Optimizing Statistical Multi- criteria Problems, using Fuzzy Goal Programming [PDF]

Muṭāli̒āt-i Mudīriyyat-i Ṣan̒atī, 2004
One of the most important issues in inventory control is determination of the reorder point. Defining parameters of this point are usually in forms of crisp or probability.

A Network Shortest Path Algorithm via Hesitancy Fuzzy Digraph

Journal of New Theory, 2019
Many extension and generalization of fuzzy sets have been studied and introduced in the literature. Hesitancy fuzzy digraph is a generalization of intuitionistic fuzzy set and fuzzy graph.  In this paper, we redefine some basic ...
