Adaptive Control with Approximated Policy Search Approach [PDF]

open access: yesITB Journal of Engineering Science, 2010
Most of existing adaptive control schemes are designed to minimize error between plant state and goal state despite the fact that executing actions that are predicted to result in smaller errors only can mislead to non-goal states. We develop an adaptive

Adaptive tracking control of nonholonomic systems: an example [PDF]

open access: yes, 1999
We study an example of an adaptive (state) tracking control problem for a four-wheel mobile robot, as it is an illustrative example of the general adaptive state-feedback tracking control problem. It turns out that formulating the adaptive state-feedback

Improved Observability in Distribution Grids Using Correlational Measurements

open access: yesIEEE Access, 2022
This paper develops a novel pseudo-measurement construct termed a Correlational Measurement (CM) to improve observability and state estimation accuracy. CMs utilize the correlation between similar classes of loads and DERs.

Evolving Nature of Human Contact Networks with Its Impact on Epidemic Processes

open access: yesComplexity, 2021
Human contact networks constitute a multitude of individuals and pairwise contacts among them. However, the dynamic nature, which generates the evolution of human contact networks, of contact patterns is unknown yet.

Adaptive conductance control

open access: yesAnnual Reviews in Control, 2022
Neuromodulation is central to the adaptation and robustness of animal nervous systems. This paper explores the classical paradigm of indirect adaptive control to design neuromodulatory controllers in conductance-based neuronal models. The adaptive control of maximal conductance parameters is shown to provide a methodology aligned with the central ...

Output Stabilization of Linear Systems in Given Set

open access: yesMathematics, 2023
This paper presents a method for designing control laws to achieve output stabilization of linear systems within specified sets, even in the presence of unknown bounded disturbances. The approach consists of two stages.

Self‐adapting control charts [PDF]

open access: yesStatistica Neerlandica, 2006
When the distributional form of the observations differs from normality, standard control charts are often prone to serious errors. Such model errors can be avoided by using (modified) nonparametric control charts. Unfortunately, these control charts suffer from large stochastic errors caused by estimation.

Robustness of higher-order networks with synergistic protection

open access: yesNew Journal of Physics, 2023
From chemical reactions to human communications, higher-order interactions are ubiquitous in real-world networks. Entities within higher-order interactions often exhibit collective behaviors that could create synergistic effects on robustness of the ...

An adjusted ELISpot-based immunoassay for evaluation of SARS-CoV-2-specific T-cell responses

open access: yesBiosafety and Health, 2022
Like antibody evaluation, using an effective antigen-specific T-cell immunity assessment method in coronavirus disease 2019 (COVID-19) patients, survivors and vaccinees is crucial for understanding the immune persistence, prognosis assessment, and ...

Network Representation Learning With Community Awareness and Its Applications in Brain Networks

open access: yesFrontiers in Physiology, 2022
Previously network representation learning methods mainly focus on exploring the microscopic structure, i.e., the pairwise relationship or similarity between nodes.
