Fast State of Charge Estimation Method for Lithium‐Ion Batteries Based on Recursive Ridge Leverage Score‐Nystrom‐Support Vector Machine

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
A state of charge (SOC) estimation method based on recursive ridge leverage score‐Nystrom‐support vector machine (RRLS‐NY‐SVM) is proposed to improve computational efficiency and robustness while maintaining high estimation accuracy. The NY approximation algorithm is adopted to directly solve the nonlinear mapping function in the original space ...

Joint Actuator and Sensor Fault Diagnosis in Wind Turbine Systems

Wind Energy, Volume 28, Issue 12, December 2025.
ABSTRACT This paper presents a fault diagnosis method for wind turbine systems that can simultaneously detect and estimate both actuator and sensor faults. Unlike previous studies that treat these faults separatelyand focus mainly on pitch angle‐related variables, our study recognizes the interdependence between actuator and sensor faults and expands ...
