Numerical Solution for Fuzzy Partial Differential Equations with Interactive Fuzzy Boundary Conditions
(2022-01-01)
This paper presents a numerical method to solve fuzzy partial differential equations, where the initial and boundary conditions are given by interactive fuzzy numbers. Interactivity is a relationship between fuzzy numbers ...
Hardware implementation of type-2 programmable fuzzifier
(2011-05-20)
The design of full programmable type-2 membership function circuit is presented in this paper. This circuit is used to implement the fuzzifier block of Type-2 Fuzzy Logic Controller chip. In this paper the type-2 fuzzy set ...
Fuzzy distributed artificial intelligence systems
(1994-12-01)
In this paper, we introduce a DAI approach called hereinafter Fuzzy Distributed Artificial Intelligence (FDAI). Through the use of fuzzy logic, we have been able to develop mechanisms that we feel may effectively improve ...
Border detection in digital images: An approach by fuzzy numbers
(2007-12-01)
The purpose of this paper is to introduce a new approach for edge detection in gray shaded images. The proposed approach is based on the fuzzy number theory. The idea is to deal with the uncertainties concerning the gray ...
Design of a simplified neuro-fuzzy system based on CMAC Architectures
(Int Inst Informatics & Systemics, 2001-01-01)
This work presents the design of a fuzzy controller with simplified architecture that use an artificial neural network working as the aggregation operator for several active fuzzy rules. The simplified architecture of the ...
Improving the stability conditions of TS fuzzy systems with fuzzy Lyapunov functions
(2011-12-01)
In this paper, the fuzzy Lyapunov function approach is considered for stabilizing continuous-time Takagi-Sugeno fuzzy systems. Previous linear matrix inequality (LMI) stability conditions are relaxed by exploring further ...
Less conservative conditions for stabilization of switched TS fuzzy systems using fuzzy Lyapunov functions
(Ieee, 2018-01-01)
Relaxed conditions to stabilize switched TS fuzzy systems are proposed. The method considers the addition of slack matrix variables to decrease the conservatism of LMI-based stability conditions. The proposed method is an ...

Fuzzy environmental quality index
(2010-11-25)
This paper presents the construction of a fuzzy environmental quality index for decision support in municipal environmental management. Five groups of indicators were selected in order to obtain an equation that best ...
An extension of the invariance principle for switched T-S fuzzy systems
(IEEEEuropean Control Association (EUCA)Zurich, 2013)
In this work, we propose an extension of the
invariance principle for switched T-S fuzzy systems using
an auxiliary function V for the convex combination of the
subsystems which applies to unstable subsystems. The ...
