Finite‐Time Disturbance Observer‐Based Nonlinear Robust Adaptive Control of Hydraulic Manipulator With Parameter Identification

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Hydraulic manipulators exhibit strong coupling, pronounced nonlinearities, and significant modeling uncertainties, which hinder high‐precision motion control. This paper proposes a finite‐time disturbance observer–based nonlinear robust adaptive control (RAC‐FTDO) framework enhanced by a physically consistent dynamic parameter identification ...

Output Feedback‐Based Direct Yaw Control System and Finite‐Time Robust Dynamic Control Allocation for Unknown Road Conditions

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This paper presents a three‐layer control architecture designed to enhance vehicle lateral stability under uncertain and varying road conditions. The system utilizes output‐feedback‐based finite‐time controllers to track the desired yaw rate and longitudinal slip in the upper and lower layers, respectively.

Evidence‐based guideline for clinical practice in the diagnosis, treatment, management, and prevention of recurrent wheezing in infants and toddlers in China

Pediatric Investigation, EarlyView.
ABSTRACT Wheezing is a common respiratory symptom in infants and toddlers, and recurrent wheezing is a significant respiratory disorder affecting this age group. Given the multifactorial etiology of recurrent wheezing, clinical practice lacks standardized diagnostic and therapeutic protocols. Recent years have witnessed substantial progress in clinical

A Self‐Supervised Machine Learning Approach for the Estimation of Open‐Circuit Voltage Degradation in Photovoltaic Systems

Progress in Photovoltaics: Research and Applications, EarlyView.
This study introduces a self‐supervised machine learning approach integrating physics‐based principles to estimate open‐circuit voltage (voc$$ {v}_{oc} $$) degradation in photovoltaic systems using SCADA data. By combining clustering and regression algorithms, our method detects performance deviations without labelled datasets.
