Considering the critical dependency of deadbeat predictive current control (DPCC) on model accuracy and the oversight of eddy current reaction in conventional permanent magnet synchronous motor (PMSM) modeling, this paper extends the vector magnetic circuit (VMC) -based PMSM model and DPCC strategy by proposing a novel generalized proportional-integral observer (GPIO) with its discrete-time implementation. From the perspective of disturbance observation and compensation performance, this paper validates the enhanced DPCC performance by incorporating the eddy current reaction in the VMC-PMSM model.
