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
