Predictive Control With Battery Power Sharing Scheme for Dual Open-End-Winding Induction Motor Based Four-Wheel Drive Electric Vehicle

For high-power electric vehicles (EVs), the drive propulsion based on induction motors is emerging as economical alternative. Compared to conventional motors, open-end winding motor (OEWIM) requires only half dc-bus voltage for given torque. The EV power train dual two-level voltage-source inverter (VSI)-fed OEWIM with isolated dc sources used in this research. uniform state-of-charge (SoC) distribution, flow from each source needs be controlled. A two-stage model-predictive direct torque control (MPDTC) scheme proposed balance SoC of batteries by proper selection VSI vectors. MPDTC free weighting factor tuning and uses a ranking method predict optimal superiority controller terms battery balancing demonstrated. performance verified FTP75 HFET driving cycles under different operating conditions, both simulation hardware experimental tests.
