In this article, an integrated driveline for electric vehicle (EV) is developed by using a symmetrical six-phase induction motor (IM). In propulsion mode, predictive torque control (PTC) is proposed to improve the dynamic performance similarly in charging mode, predictive current control is implemented. The conventional PTC (C-PTC) in propulsion mode generates $xy$ -subspace flux and provides variable switching frequency with a high computational burden. Modified PTC (M-PTC) with only torque and flux as a constraint variable with constant switching frequency operation is implemented. In this method, $xy$ -subspace is eliminated by using synthetic voltage vectors, and the computational burden is also reduced by adopting stator flux monitoring in $dq$ -subspace. The switching sequence with the minimum transition while a digital signal processor (DSP) implementation is feasible due to redundancy in synthetic voltage vectors. In the charging mode, the same high rating driveline inverter is utilized as a rectifier. In this mode, stator windings are reconfigured to provide grid interfacing inductance, while the rotor is maintained in stationary position due to transfer of excitation from torque producing ( $dq$ ) plane to nontorque producing ( $xy$ ) plane. This controller also provides a constant switching frequency operation. The comparative analysis, along with experimental results, is provided to validate the effective predictive control during both operating modes.
