Sliding‐Mode Control of Electromagnetic Suspension Systems Considering Disturbance Compensation

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study proposes an integrated control strategy for magnetic levitation systems, combining a cascaded linear extended state observer with an improved sliding‐mode control. This method accurately estimates and compensates for disturbances, significantly enhancing suspension stability and rejection capability.

An Adaptive Pitch Control Strategy for Wind Turbines Using PIO‐Optimized Parallel Observation Deviation‐Coupled Linear Active Disturbance Rejection Control

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This study proposes a parallel observation deviation‐coupled linear active disturbance rejection control (PODC‐LADRC) strategy optimized by a pigeon‐inspired optimization algorithm to mitigate asymmetric aerodynamic loads in large‐scale wind turbines. By utilizing a decoupled observation architecture, the proposed method reconstructs total disturbances

Spin current shot noise as a probe of interactions in mesoscopic systems

, 2003
It is shown that the spin resolved current shot noise can probe attractive or repulsive interactions in mesoscopic systems. This is illustrated in two physical situations : i) a normal-superconducting junction where the spin current noise is found to be ...

Overvoltage Suppression Strategy for HPFC Based on Bandwidth Adaptive LADRC and Improved Reactive Power Control

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
Overvoltage occurs in Hybrid Power Flow Controllers (HPFC) under specific fault conditions. This paper proposes a linear Active Disturbance Rejection (LADRC) strategy integrating reactive power adaptive regulation and bandwidth parameter adaptive adjustment to suppress whole‐process overvoltage in HPFC.

An Overcurrent Suppression Strategy for Distributed Photovoltaic Inverters Under Unbalanced Faults Based on Adaptive Linear Active Disturbance Rejection Control

IET Smart Grid, Volume 9, Issue 1, January/December 2026.
After distributed photovoltaic (PV) systems are connected to the distribution network, the overcurrent problem caused by transient faults instantaneously threatens the safety of PV inverters and other equipment. This paper proposes a comprehensive control method that combines active‐loop adaptive linear active disturbance rejection control (A‐LADRC ...
