摘要： A motor control system and method are provided for a vehicle that reduces torque ripples due to motor system characteristics while the vehicle is running at ultra-low speed in an electric vehicle running mode. The system includes a current command generator that generates a current command based on a torque command, a motor speed, and a reference voltage. A current controller generates a voltage command based on the current command. A coordinate transformer transforms the voltage command into a 3-phase voltage command by a coordinate transformation and a PWM (pulse width modulation) signal generator generates a switch signal based on the 3-phase voltage command. A PWM inverter generates a 3-phase driving current to drive a motor based on the switch signal and a current control ripple compensator applies a reverse phase harmonic wave to the current controller to reduce a harmonic wave caused by errors generated from the current controller.
