Extended State Observer-Based Sliding Mode Control Design of Two-DOF Lower Limb Exoskeleton

Actuators, 2023
Due to some model uncertainties and unknown friction disturbances that exist in the 2-DOF lower limb exoskeleton, a linear extended state observer (LESO) is proposed to estimate the unmeasurable angular velocity of two joints and the lumped uncertainties

Sleep Traits and Cognitive Function: A Prospective Cohort Study With Exploration of Inflammatory Biomarkers

Brain and Behavior, Volume 16, Issue 6, June 2026.
ABSTRACT Introduction Although sleep disturbance is closely linked to cognitive impairment, the specific sleep‐related characteristics driving this deficit remain undetermined, with the mechanistic contribution of biomarkers also poorly characterized.

Century‐long trends in plant diversity of temperate mountain vegetation are modulated along elevation gradient

Journal of Ecology, Volume 114, Issue 3, March 2026.
Resurvey studies in mountain forests of the Tatra Mountains (Central Europe) show that plant diversity has increased over the past century, particularly at lower elevations. These shifts were associated more with increased nitrogen deposition and reduced grazing pressure than with direct climate warming.

Phase‐Advanced ADRC: Precision Missile Attitude Control via Delay Compensation

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes measurement delay compensated phase‐leading linear active disturbance rejection control (MPLADRC) with a novel observer (MPLESO) integrating synchronized input filtering and phase‐lead compensation. This framework eliminates temporal signal mismatch and phase lag in missile attitude control, achieving zero steady‐state error for ...

Hierarchical Estimation–Based Observer Method for Robust Oxygen Excess Ratio Control in PEM Fuel Cell Systems

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This study proposes a recursive hierarchical observer combining an extended Kalman filter, extended state observer and weighted least‐squares algorithm to accurately estimate the oxygen excess ratio in polymer electrolyte membrane fuel cells under challenging low‐current and noisy conditions.

Damping Compensation for Active Vibration Isolation System With Active Disturbance Rejection Control

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
The analysis of classic active disturbance rejection control (ADRC) for active vibration isolation systems (AVIS) with electromagnetic actuators demonstrates that directly applying ADRC to these systems has some shortcomings. To overcome the limitations of classic ADRC in AVIS with electromagnetic actuators, damping compensation is proposed to enhance ...
