A Minimum-Footprint Implementation of Discrete-Time ADRC [PDF]

2021 European Control Conference (ECC), 2021
To foster the adoption of active disturbance rejection control (ADRC) and support its deployment even on low-cost embedded systems, this article introduces the most efficient implementation of linear discrete-time ADRC to date. While maintaining all features and the exact performance characteristics of the state-space form, computational efforts and ...

Combined ADRC and Model reference-based input filter for Overhead crane control: Design and experimental validation [PDF]

FME Transactions
Overhead cranes are widely used in industry and transportation, but their operation is often affected by undesired payload oscillations that degrade maneuverability and safety. Although numerous control strategies have been investigated, most of them are

Creation and analysis of a ‘national’ homelessness prevention programme dataset – The Supporting People Data Linkage Study

International Journal of Population Data Science, 2018
Background Welsh Government (WG) invests over £120m annually in housing related support to help prevent and tackle homelessness under the Supporting People (SP) Programme. A 2016 data-linkage Feasibility Study for two Local Authorities (LAs) indicated

Model-Based Control with Active Disturbance Rejection Algorithm for a Diesel Engine

Complexity, 2023
To improve the speed control performance of a diesel engine, the active disturbance rejection controller (ADRC) is designed by adding an arranging transition process to the traditional PID controller, extracting differential signals reasonably, and ...

The Booting‐Type ADRC of Airborne Photoelectrical Platform [PDF]

Mathematical Problems in Engineering, 2014
Customary disturbance rejection in the photoelectrical platform is “passive,” which makes it difficult to further improve the isolation degree owning to the strict restriction of mechanical resonance frequency. In this paper, a booting‐type ADRC is proposed, whose disturbance estimation process is guided by target value to reduce the overshoot and lag ...

Probabilistic linkage to enhance deterministic algorithms and reduce data linkage errors in hospital administrative data

Journal of Innovation in Health Informatics, 2017
Background: The pseudonymisation algorithm used to link together episodes of care belonging to the same patient in England [Hospital Episode Statistics ID (HESID)] has never undergone any formal evaluation to determine the extent of data linkage error ...

Does change in area-level deprivation, change health outcomes? A latent class growth analysis of population data

International Journal of Population Data Science
Objectives Trajectories of social mobility may be a more informative predictor of health than point-in time analyses. We sought to identify area-level deprivation trajectories within the Northern Ireland (NI) population and their associations with ...

Social and spatial mobility and self-reported heath in older-age: linkage of the Scottish Longitudinal Study to the Scottish Mental Survey 1947

International Journal of Population Data Science, 2018
Background There is debate within the literature as to whether social mobility inflates or constrains health inequalities. The role of geographical mobility is unknown.

Invariance Principle and ADRC Development

IOP Conference Series: Earth and Environmental Science, 2019
After reading a lot of data, the author believes that cybernetics will change from the model theory of direct control deviation to the cybernetics of controlling internal and external disturbances according to the invariance theory in the future. Since Watt's steam engine in 1788, the theory of automatic control has developed rapidly.
