PMSM FOC Control MATLAB Code for EV Applications
Field-oriented control is widely used for high-performance PMSM traction drives because torque and flux can be regulated through dq-axis current control. For EV research, the controller should be evaluated together with the inverter, motor parameters and vehicle/load demand.
Research problem
The objective is to track speed or torque over a drive cycle while limiting current, torque ripple and transient error. EV applications also require attention to regenerative operation, DC-bus limits and efficiency across a wide speed range.
FOC control structure
Use Clarke/Park transforms, id/iq current controllers, speed PI or advanced outer-loop control, inverse transforms, SVPWM and an inverter-fed PMSM model. Rotor position can be measured or estimated depending on the research scope.
EV test cases
Evaluate acceleration, load torque steps, base-speed to field-weakening transition and regenerative braking. For a vehicle-level study, feed the motor demand from longitudinal vehicle dynamics or a drive-cycle reference.
Results to compare
Plot speed tracking, electromagnetic torque, id/iq currents, three-phase currents, DC-link power, controller outputs and efficiency or losses when available.

Frequently asked questions
For many surface-PMSM operating regions, id=0 gives simple torque-per-ampere operation. IPMSM or field-weakening studies may require nonzero id references.
Yes. Keep the same motor, inverter and test profile so improvements in transient response, ripple or robustness can be compared fairly.
