IET Electric Power Applications, Volume 18, Issue 11, Page 1421-1434, November 2024.To enhance the performance of the flux observer in mitigating DC bias and high‐order harmonics, this study introduces a fourth‐ordered flux observer (FOIFFO). Theoretical analysis demonstrates that the FOIFFO exhibits robust attenuation capabilities towards DC bias and harmonics, thereby preventing motor parameter mismatch and additional interference ...
