Vector Control Model for Permanent Magnet Synchronous Motors

Permanent Magnet Synchronous Motors (PMSM) are widely used in power systems across various applications including electric vehicles, rail transportation, industrial manufacturing, and household appliances. The vector control model represents a common control methodology that achieves high-precision regulation of motor speed and torque by controlling the motor's current and magnetic flux. This control strategy typically implements Clarke and Park transformations to convert three-phase currents into a rotating reference frame, enabling independent control of torque and flux components. Through closed-loop speed control using PI regulators, the system can finely adjust PWM signals to the inverter, ensuring accurate tracking of reference speeds. This approach allows for superior control of PMSMs, effectively achieving control objectives while enhancing motor efficiency and performance through advanced algorithms like field-oriented control (FOC).
