Repetitive Fractional-Order Active Disturbance Rejection Control for Permanent Magnet Synchronous Motor

Machines
In order to reduce the impact of various disturbances on the permanent magnet synchronous motor (PMSM) system especially during low-speed (0–300 rpm), this paper proposes a novel repetitive fractional-order active disturbance rejection control (RFO-ADRC)

AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.

Longitudinal associations of rapid eye movement (REM) sleep and slow‐wave sleep with plasma Alzheimer's disease biomarkers

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract INTRODUCTION Data on how sleep architecture relates to progression of plasma Alzheimer's disease biomarkers remains limited. METHODS Sixty‐four cognitively unimpaired older adults (ages 55–90) underwent plasma collection twice 2.6 years apart and polysomnography proximate to the first plasma collection.
