Signed Decomposition of Fully Fuzzy Linear Systems
System of linear equations is applied for solving many problems in various areas of applied sciences. Fuzzy methods constitute an important mathematical and computational tool for modeling real-world systems with uncertainties of parameters. In this paper, we discuss about fully fuzzy linear systems in the form AX = b (FFLS). A novel method for finding the non-zero fuzzy solutions of these systems is proposed. We suppose that all elements of coefficient matrix A are positive and we employ parametric form linear system. Finally, Numerical examples are presented to illustrate this approach and its results are compared with other methods
Control of the Reliability of Textual Information in Documents Based on Neuro-Fuzzy Identification
Constructive approaches, methods, algorithms and a software package for improving the reliability of transmission and processing of electronic documents in electronic document management systems based on soft computing have been developed. The methods of parametric identification, linear, non-linear functional dependencies, identifiers and approximators of fuzzy models, as well as neural networks have been studied. Knowledge bases of fuzzy rules and databases are implemented. Modified operators of the genetic algorithm are proposed, which are tied into the structure of mechanisms for fuzzy control of the reliability of texts of electronic documents
Sensitivity Study of a Class of Fuzzy Control Systems
The paper performs the sensitivity study with respect to the parametric
variations of the controlled plant in case of a class of fuzzy control
systems dedicated to servo systems. The presentation is particularized to
fuzzy control systems to solve the tracking control problem in case of
wheeled mobile robots of tricycle type with two degrees of freedom. There is
proposed a new development method for Takagi-Sugeno PI-fuzzy controllers
based on the application of the Extended Symmetrical Optimum method to the
basic linear PI controllers in a cascaded control system structure. There
are derived sensitivity models, validated by considering a case study
concerning the speed control of a servo system with DC motor as actuator in
mobile robot control. Experimental results validate the development method
for Takagi-Sugeno PI-fuzzy controllers
General Dual Fuzzy Linear Systems
Abstract This paper mainly intends to discuss the solution of fully fuzzy linear systems (FFLS) Ax + b = Cx + d, where A and C are fuzzy matrices, b and d are fuzzy vectors. We transform the systems by using fuzzy numbers with a new parametric form for finding a fuzzy vector x that satisfies in the system
