Robust control of a single-ended primary inductor converter using adrc technique

Engineering Research Express, 2023
Control of a single-ended primary inductor converter (SEPIC) is a challenging task as it is a fourth-order non-linear system. In this paper, an active disturbance rejection control (ADRC) scheme is proposed for the SEPIC converter with a high switching ...

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 ...

Active disturbance rejection position servo control of PMSLM based on reduced-order extended state observer

Chinese Journal of Electrical Engineering, 2020
To enhance the control accuracy of permanent magnet synchronous linear motor (PMSLM) servo systems affected by disturbances, such as time-varying parameters and abrupt load changes, an active disturbance rejection control (ADRC) algorithm based on a ...

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.

Attitude Stabilization Control of Autonomous Underwater Vehicle Based on Decoupling Algorithm and PSO-ADRC

Frontiers in Bioengineering and Biotechnology, 2022
Autonomous Underwater Vehicle are widely used in industries, such as marine resource exploitation and fish farming, but they are often subject to a large amount of interference which cause poor control stability, while performing their tasks.

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.

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 ...
