Direct-drive in-wheel motors have become an extremely attractive option for electric vehicles. Two kinds of motors are devised, Permanent Magnet Synchronous Motor (PMSM) and Permanent-Magnet Flux-Modulated Motor (PMFM), respectively. Keeping the same back EMF, current density and copper loss, this paper analyzes and compares torque density, torque ripple, flux-weakening performance, speed range, loss...
The paper proposes a moving average filter (MAF)-based model predictive control (MPC) for the electric vehicles (EVs) bidirectional chargers. Grid virtual flux is used to estimate the grid voltage through a low pass filter (LPF). An MAF, which acts as an ideal LPF, can eliminate the effect of unbalanced/distorted grid voltage and unknown characteristic harmonics. Both the two-cascaded LPF-based and...
