A parameter formula connecting PID and ADRC [PDF]

Science China Information Sciences, 2020
This paper presents a parameter formula connecting the well-known proportional-integralderivative (PID) control and the active disturbance rejection control (ADRC). On the one hand, this formula gives a quantitative lower bound to the bandwidth of the extended state observer (ESO) used in ADRC, implying that the ESO is not necessarily of high gain.

Blood-based proteomic signature of amyloidosis: identification of novel regulators of amyloid load. [PDF]

Alzheimers Dement
Abstract INTRODUCTION Cerebral amyloidosis is a defining feature of Alzheimer's disease (AD), yet the molecular heterogeneity among amyloidbeta‐positive (Aβ+) individuals remains poorly defined. We aimed to map the proteomic correlates of cerebral amyloidosis and link them to clinical variability within Aβ+ individuals.

Evaluating the accuracy and reliability of telephone-derived Clinical Dementia Rating scores: A comparative analysis with in-person assessments. [PDF]

Alzheimers Dement
Abstract INTRODUCTION The Clinical Dementia Rating (CDR) scale typically is administered in person, but use of telephone‐based, informant‐only assessments increased during the coronavirus disease 2019 (COVID‐19) pandemic. The correspondence of informant‐only assessments with in‐person ratings remains unclear.

Generalized Proportional–Integral–Derivative Interpretation of a Class of Improved Two-Degree-of-Freedom Controllers [PDF]

Sensors
In the framework of the traditional active disturbance rejection controller (ADRC), the state error feedback utilizes estimated values from the extended state observer, which may introduce phase lag.

ADRC in output and error form: connection, equivalence, performance

Control Theory and Technology, 2023
In this work, we investigate two specific linear ADRC structures, namely output- and error-based. The former is considered a 'standard' version of ADRC, a title obtained primarily thanks to its simplicity and effectiveness, which have spurred its adoption across multiple industries. The latter is found to be especially appealing to practitioners as its

Simultaneous Assessment of Intracranial Artery and Paravascular CSF Pulsation Using 3D Whole-Brain Diffusion-Prepared Cine bSSFP (DECAF) MRI. [PDF]

Magn Reson Med
ABSTRACT Purpose To propose a noninvasive and quantitative MRI approach to simultaneously assessing intracranial artery pulsation and paravascular cerebrospinal fluid (CSF) pulsation in the human brain. Methods We developed a 3D whole‐brain Diffusion‐prepared Cine bSSFP (DECAF) MRI technique, with improved motion‐sensitized driven‐equilibrium providing

UAV trajectory tracking based on ADRC control algorithm [PDF]

ITM Web of Conferences, 2022
UAV flying in the air is affected by external airflow factors, and the system has the characteristics of underdrive, nonlinear and uncertainty, which makes the flight state of the UAV become complicated. The trajectory tracking of UAV is studied by using

Active disturbance rejection control-based anti-coupling method for conical magnetic bearings

Acta Polytechnica, 2022
Conical-shape magnetic bearings are currently a potential candidate for various magnetic force-supported applications due to their unique geometric nature reducing the number of required active magnets.

Tuning and implementation variants of discrete-time ADRC

Control Theory and Technology, 2023
Practical implementations of active disturbance rejection control (ADRC) will almost always take place in discretized form. Since applications may have quite different needs regarding their discrete-time controllers, this article summarizes and extends the available set of ADRC implementations to provide a suitable variant for as many as possible use ...

Combining deterministic and probabilistic matching to reduce data linkage errors in hospital administrative data

International Journal of Population Data Science, 2017
Objectives Data linkage algorithms are used to link together multiple episodes of care belonging to the same patient. For example, the HESID algorithm is used to generate Hospital Episode Statistics (HES) in England.
