Identification of Multiple Input-multiple Output Non-linear System Cement Rotary Kiln using Stochastic Gradient-based Rough-neural Network [PDF]

open access: yesJournal of Artificial Intelligence and Data Mining, 2020
Because of the existing interactions among the variables of a multiple input-multiple output (MIMO) nonlinear system, its identification is a difficult task, particularly in the presence of uncertainties.

Theory of System Identification and Adaptive Control for Stochastic Systems *

open access: yesIFAC Proceedings Volumes, 1988
Abstract This paper presents a series of theoretical results on parameter identification and adaptive control for discrete-time stochastic feedback control systems. Without a use of persistent excitation condition the unknown coefficients of the system are consistently estimated by use of the extended least squares (ELS) and the stochastic gradient ...

Auxiliary Model-Based Multi-Innovation Fractional Stochastic Gradient Algorithm for Hammerstein Output-Error Systems

open access: yesMachines, 2021
This paper focuses on the nonlinear system identification problem, which is a basic premise of control and fault diagnosis. For Hammerstein output-error nonlinear systems, we propose an auxiliary model-based multi-innovation fractional stochastic ...

A Fast and Generic Method to Identify Parameters in Complex and Embedded Geophysical Models: The Example of Turbulent Mixing in the Ocean

open access: yesJournal of Advances in Modeling Earth Systems, 2021
Geophysical models make predictions relying on parameter values to be estimated from data. However, existing methods are costly because they require either many runs of the complex geophysical model or to implement an adjoint model.

Determination of the Concentration of Propionic Acid in an Aqueous Solution by POD-GP Model and Spectroscopy

open access: yesEnergies, 2021
Biorefining and biorefineries are the future of industry and energy. It is still a long way to complete its implementation, but small biorefineries focused mainly on the production of fuels and energy are more and more frequent in rural areas and large ...

Identification and Stochastic Optimizing the UAV Motion Control in Turbulent Atmosphere

open access: yesVolume 02 Issue 02, 2021
In a class of diffusion Markov processes, we formulate a problem of identification of nonlinear stochastic dynamic systems with random parameters, multiplicative and additive noises, control functions, and the state vector at a final time moment.

Combined system of extreme control of mineralized water dilution in river basins

open access: yesМеліорація і водне господарство, 2021
The theory of combined systems of extreme control, which is used in technical systems, was developed and adapted in socio-ecological-economic systems. For example, river basins are such systems.

Effective Connectivity Changes among Brain Hierarchical Architecture of Pre-Supplementary Motor Area in Taxi Drivers

open access: yesApplied Sciences, 2023
Much effort has been devoted towards the identification of brain areas recruited during driving—as one of the most common motor skills of human beings. However, how driving experience impacts on the brain’s intrinsic functional architecture has not been ...

Parameter Identification and the Finite-Time Combination–Combination Synchronization of Fractional-Order Chaotic Systems with Different Structures under Multiple Stochastic Disturbances

open access: yesMathematics, 2022
This paper researches the issue of the finite-time combination-combination (C-C) synchronization (FTCCS) of fractional order (FO) chaotic systems under multiple stochastic disturbances (SD) utilizing the nonsingular terminal sliding mode control (NTSMC ...
