Linear Extended State Observer-Based Backstepping Sliding Mode Control For DC-Bus Voltage Regulation Under Constant Power Loads In DC Microgrids

Journal of Applied Science and Engineering
In DC microgrids, Constant Power Load (CPL) is one of the causes to generate negative incremental resistance, which significantly reduces the stability margin and may lead to DC-bus voltage fluctuations.

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

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.
