Patent ID: 8664900

Claim:
A system for controlling a motor of a hybrid vehicle, comprising: a current order generator determining currents of a first axis and a second axis according to a driving condition; a current controller generating voltages of the first and second axes by using the currents of the first and second axes determined by the current order generator and feedback currents of the first and second axes; a coordinate transformer converting the voltages of the first and second axes into 3-phase voltage, and converting 3-phase feedback current into the feedback currents of the first and second axes and transmitting the feedback currents of the first and second axes to the current controller; a signal generator receiving the 3-phase voltage from the coordinate transformer and generating 3-phase signal corresponding thereto; a PWM inverter generating 3-phase current based on the 3-phase signal, and transmitting the 3-phase current to the coordinate transformer as the 3-phase feedback current; a motor driven by receiving the 3-phase current from the PWM inverter; and a resolver detecting phase of the motor and transmitting the phase of the motor to the current order generator and the coordinate transformer, wherein the current order generator comprises a reference current determination module determining reference currents of the first and second axes, a compensation value determination module determining compensation values of the reference currents of the first and second axes, and a current determination module determining the currents of the first and second axes from the reference currents of the first and second axes and the compensation values of the reference currents of the first and second axes.
