What are the main motor control strategies used in EV drives?

Key motor control strategies include: Field-Oriented Control (FOC) using Park/Clarke transforms to control d-q axis currents independently for optimal torque production, Direct Torque Control (DTC) directly controlling flux and torque without current loops for faster response, Maximum Torque Per Amp (MTPA) optimization minimizing current for given torque, and field weakening extending speed range beyond base speed by reducing magnetic flux. Modern controllers implement these using high-speed DSPs with switching frequencies of 8-20 kHz, achieving smooth, efficient operation across the operating range.
