A special method for fuzzy-logic-based system modeling is presented to develop multi-variable fuzzy models on the basis of the system's measured input and output data. The global modeling problem is proposed to be solved in two steps: by fuzzy model connguration and fuzzy model identiication. The fuzzy model connguration procedure is characterized by preliminary considerations leading to the de...

In this paper, we compare four methods to perform eye-to-hand visual servoing using primitive tactile information. They are relative visual servoing, direct fuzzy servoing, fuzzy correction, and interpolation. These methods just need a monocular eye-to-hand camera and primitive tactile sensors. The fuzzy methods are tuned [1] by an Adaptive Neuro-Fuzzy Inference System (ANFIS). The set-up is pa...

In general fuzzy sets are used to analyze the fuzzy system reliability. Here intuitionistic fuzzy set theory for analyzing the fuzzy system reliability has been used. To analyze the fuzzy system reliability, the reliability of each component of the system as a triangular intuitionistic fuzzy number is considered. Triangular intuitionistic fuzzy number and their arithmetic operations are introdu...

Turbo-expanders are used in industries for cooling, liquefaction and also power generation. An important part of these turbines is the variable angle nozzle causing a nonlinear behavior that is not well recognized among the prime movers of the dispersed generators. In this paper, at first, the turbo expander system is evaluated in details and its nonlinear behavior is investigated. Then, the sy...

In this paper, we study a coupled system of nonlinear fractional differential equations with multi-point boundary condi- tions. The differential operator is taken in the Riemann-Liouville sense. Applying the Schauder fixed-point theorem and the contrac- tion mapping principle, two existence results are obtained for the following system D^{alpha}_{0+}x(t)=fleft(t,y(t),D^{p}_{0+}y(t)right), t in (0,...

The aim of this paper is to develop a methodology for solving matrix games with payoffs of trapezoidal intuitionistic fuzzy numbers (TrIFNs). In this methodology, the concepts of TrIFNs and solutions for matrix games with payoffs of TrIFNs are defined. Two new auxiliary intuitionistic fuzzy nonlinear programming models are hereby constructed to solve matrix games with payoffs of TrIFNs. Using a...

A fuzzy number is simply an ordinary number whose precise value is somewhat uncertain. Fuzzy numbers are used in statistics, computer programming, engineering, and experimental science. The arithmetic operators on fuzzy numbers are basic content in fuzzy mathematics. Operation of fuzzy number can be generalized from that of crisp interval. The operations of interval are discussed. Multiplicatio...
