Weakly fuzzy topological entropy [PDF]

open access: yesMathematica Bohemica, 2022
In 2005, İ. Tok fuzzified the notion of the topological entropy R. A. Adler et al. (1965) using the notion of fuzzy compactness of C. L. Chang (1968).

On Controllability and Observability of Fuzzy Dynamical Matrix Lyapunov Systems

open access: yesAdvances in Fuzzy Systems, 2008
We provide a way to combine matrix Lyapunov systems with fuzzy rules to form a new fuzzy system called fuzzy dynamical matrix Lyapunov system, which can be regarded as a new approach to intelligent control. First, we study the controllability property of

Model-Based Application of Fuzzy Control to a Class of Industrial Process Operation Systems With Uncertainty

open access: yesIEEE Access, 2018
In this paper, the model-based fuzzy control application for double-layer operation systems with uncertainty is addressed. Due to the multiple-time scales of complex industrial systems, as well as the inborn uncertainties of the system, the challenge of ...

Synthesis of a Dynamical Output ${H}_{\infty}$ Controller for the Fuzzy Input-Output Model

open access: yesIEEE Access, 2019
In this paper, the issue of dynamical output H∞ controller designing is addressed for the fuzzy input-output (FIO) model. The FIO model is significantly distinctive from the conventional Mamdani and T-S or T-S-K fuzzy models and can be ...

Dynamical analysis and adaptive fuzzy control for the fractional-order financial risk chaotic system

open access: yesAdvances in Difference Equations, 2020
In this paper, a fractional-order model of a financial risk dynamical system is proposed and the complex behavior of such a system is presented. The basic dynamical behavior of this financial risk dynamic system, such as chaotic attractor, Lyapunov ...

Stationary Points—I: One-Dimensional p-Fuzzy Dynamical Systems

open access: yesJournal of Applied Mathematics, 2013
p-Fuzzy dynamical systems are variational systems whose dynamic is obtained by means of a Mamdani type fuzzy rule-based system. In this paper, we will show the 1-dimensional p-fuzzy dynamical systems and will present theorems that establish conditions of

Logical Entropy of Dynamical Systems—A General Model

open access: yesMathematics, 2017
In the paper by Riečan and Markechová (Fuzzy Sets Syst. 96, 1998), some fuzzy modifications of Shannon’s and Kolmogorov-Sinai’s entropy were studied and the general scheme involving the presented models was introduced.
