Sampling error-based model-free predictive current control of open-end winding induction motor with simplified vector selection
(2023-03)
A sampling error-based finite-set predictive current control (FS-PCC) is proposed in this article for the open-end winding induction motor (OEWIM) drive. The proposed scheme controls the zero-sequence current (ZSC) alongside ...
