Black-Box Fuzzy Identification of a Nonlinear Hydrogen Fuel Cell Model

Trends in Computational and Applied Mathematics, 2018
A fuzzy  identification of the dynamical system  model is developed upon a data generated by a software simulator of a hydrogen fuel cell. The data presents a black box  model, just composed by inputs and outputs, carry no  additional information, and ...

Security SMC for Networked Fuzzy Singular Systems With Semi-Markov Switching Parameters

IEEE Access, 2022
In this paper, the issue of security sliding mode control (SMC) is addressed for networked nonlinear singular systems with semi-Markov switching parameters via the Takagi-Sugeno (T-S) fuzzy strategy.

Application of the Extended Kalman filter to fuzzy modeling: Algorithms and practical implementation [PDF]

, 2011
Modeling phase is fundamental both in the analysis process of a dynamic system and the design of a control system. If this phase is in-line is even more critical and the only information of the system comes from input/output data.

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

International Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

Fuzzy Symbolic Dynamics for Neurodynamical Systems [PDF]

, 2008
Neurodynamical systems are characterized by a large number of signal streams, measuring activity of individual neurons, local field potentials, aggregated electrical (EEG) or magnetic potentials (MEG), oxygen use (fMRI) or concentration of radioactive traces (PET) in different parts of the brain.

Approximate Controllability of Semi-linear Fuzzy Dynamical System [PDF]

, 2016
In this paper we consider a semi-linear dynamical system with fuzzy initial condition. We discuss the results regarding the approximate controllability of the system and existence of the controller which steers the system to the desired state. The theory

A new approach to adaptive fuzzy control: the controller output error method [PDF]

, 1997
The controller output error method (COEM) is introduced and applied to the design of adaptive fuzzy control systems. The method employs a gradient descent algorithm to minimize a cost function which is based on the error at the controller output.

An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing

Advanced Functional Materials, EarlyView.
Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...

Matrix formulation of fuzzy rule-based systems [PDF]

, 1996
In this paper, a matrix formulation of fuzzy rule based systems is introduced. A gradient descent training algorithm for the determination of the unknown parameters can also be expressed in a matrix form for various adaptive fuzzy networks.
