A method for controlling motor, the method including, receiving a motor torque command, calculating a first current associated with the motor torque command, calculating an estimated first current responsive to receiving a first regulated voltage associated with the first current and a motor speed signal, subtracting the estimated first current from the first current resulting in a first current error signal, and outputting the first regulated voltage to a voltage controller responsive to receiving the first current error signal, the estimated first current, and the motor speed signal.
