BEHAVIOR OF SOLUTIONS TO A FUZZY NONLINEAR DIFFERENCE EQUATION

Qianhong Zhang; Lihui Yang; Daixi Liao

Volume 9, Issue 2 , May and June 2012, Pages 1-12

Abstract
  In this paper, we study the existence, asymptotic behavior of the positive solutions of a fuzzy nonlinear difference equation$$ x_{n+1}=frac{Ax_n+x_{n-1}}{B+x_{n-1}}, n=0,1,cdots,$$ where $(x_n)$ is a sequence of positive fuzzy number, $A, B$ are positive fuzzy numbers and the initial conditions ...  Read More

Gui-jun Wang; Xiao-ping Li

Volume 9, Issue 2 , May and June 2012, Pages 13-24

Abstract
  The generalized fuzzy valued $\theta$-Choquet integrals will beestablished for the given $\mu$-integrable fuzzy valued functionson a general fuzzy measure space, and the convergence theorems ofthis kind of fuzzy valued integral are being discussed.Furthermore, the whole of integrals is regarded as a ...  Read More

OPTIMIZED FUZZY CONTROL DESIGN OF AN AUTONOMOUS UNDERWATER VEHICLE

Behrooz Raeisy; Ali Akbar Safavi; Ali Reza Khayatian

Volume 9, Issue 2 , May and June 2012, Pages 25-41

Abstract
  In this study, the roll, yaw and depth fuzzy control of an Au- tonomous Underwater Vehicle (AUV) are addressed. Yaw and roll angles are regulated only using their errors and rates, but due to the complexity of depth dynamic channel, additional pitch rate quantity is used to improve the depth loop performance. ...  Read More

NON-FRAGILE GUARANTEED COST CONTROL OF T-S FUZZY TIME-VARYING DELAY SYSTEMS WITH LOCAL BILINEAR MODELS

Junmin Li; Guo Zhang

Volume 9, Issue 2 , May and June 2012, Pages 43-62

Abstract
  This paper focuses on the non-fragile guaranteed cost control problem for a class of T-S fuzzy time-varying delay systems with local bilinear models. The objective is to design a non-fragile guaranteed cost state feedback controller via the parallel distributed compensation (PDC) approach such that the ...  Read More

Statistical Convergence and Strong $p-$Ces`{a}ro\ Summability of Order $beta$ in Sequences\ of Fuzzy Numbers

H. Altinok; Y. Altin; M. Isik

Volume 9, Issue 2 , May and June 2012, Pages 63-73

Abstract
  In this study we introduce the concepts of statistical convergence of order$beta$ and strong $p-$Ces`{a}ro summability of order $beta$ for sequencesof fuzzy numbers. Also, we give some relations between the statisticalconvergence of order $beta$ and strong $p-$Ces`{a}ro summability of order$beta$ and ...  Read More

A MODIFICATION ON RIDGE ESTIMATION FOR FUZZY NONPARAMETRIC REGRESSION

Rahman Farnoosh; Javad Ghasemian; Omid Solaymani Fard

Volume 9, Issue 2 , May and June 2012, Pages 75-88

Abstract
  This paper deals with ridge estimation of fuzzy nonparametric regression models using triangular fuzzy numbers. This estimation method is obtained by implementing ridge regression learning algorithm in the La- grangian dual space. The distance measure for fuzzy numbers that suggested by Diamond is used ...  Read More

Delay-dependent robust stabilization and $H_{infty}$ control for uncertain stochastic T-S fuzzy systems with multiple time delays

T. Senthilkumar; P. Balasubramaniam

Volume 9, Issue 2 , May and June 2012, Pages 89-111

Abstract
  In this paper, the problems of robust stabilization and$H_{infty}$ control for uncertain stochastic systems withmultiple time delays represented by the Takagi-Sugeno (T-S) fuzzymodel have been studied. By constructing a new Lyapunov-Krasovskiifunctional (LKF) and using the bounding techniques, sufficientconditions ...  Read More

ON GENERALIZED FUZZY MULTISETS AND THEIR USE IN COMPUTATION

Apostolos Syropoulos

Volume 9, Issue 2 , May and June 2012, Pages 113-125

Abstract
  An orthogonal approach to the fuzzification of both multisets and hybridsets is presented. In particular, we introduce $L$-multi-fuzzy and$L$-fuzzy hybrid sets, which are general enough and in spirit with thebasic concepts of fuzzy set theory. In addition, we study the properties ofthese structures. ...  Read More

GLOBAL ROBUST STABILITY CRITERIA FOR T-S FUZZY SYSTEMS WITH DISTRIBUTED DELAYS AND TIME DELAY IN THE LEAKAGE TERM

P. Balasubramaniam; S. Lakshmanan; R. Rakkiyappan

Volume 9, Issue 2 , May and June 2012, Pages 127-146

Abstract
  The paper is concerned with robust stability criteria for Takagi- Sugeno (T-S) fuzzy systems with distributed delays and time delay in the leakage term. By exploiting a model transformation, the system is converted to one of the neutral delay system. Global robust stability result is proposed by a new ...  Read More

Volume 9, Issue 2 , May and June 2012, Pages 147-161

Abstract
  Based on a complete Heyting algebra, we modify the definition oflattice-valued fuzzifying convergence space using fuzzy inclusionorder and construct in this way a Cartesian-closed category, calledthe category of $L-$ordered fuzzifying convergence spaces, in whichthe category of $L-$fuzzifying topological ...  Read More
