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

open access: yesSensors
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.

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

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 2, Page 727-740, August 2026.
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

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

open access: yes2021 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 ...
