A Novel Hybrid Robust Transfer Learning‐Based Adaptive Fractional‐Order Super‐Twisting Sliding Mode Controller Enhanced for Speed Regulation of Brushless DC Motor

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
The incorporation of fractional‐order (FO) dynamics adds flexibility, noise resilience and adaptability but FO controllers are still based on offline gain tuning and can't be used in practice. In order to overcome all these challenges, a novel transfer learning‐based fractional‐order super‐twisting sliding mode controller (TL‐FO‐ST‐SMC) is proposed in ...
