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 ...

Brushless doubly-fed machines: Opportunities and challenges [PDF]

Chinese Journal of Electrical Engineering, 2018
The brushless doubly-fed machine(BDFM) is a family of multiport electric machines with two ac electrical ports and a common mechanical port. Different from the conventional singly-fed machines whose synchronous speed is solely determined by a single supply frequency and the actual pole pair number, the BDFM has two supply frequencies and two different ...
