摘要： In a control apparatus, a target harmonic current obtainer obtains, according to a phase current flowing through at least one phase winding of a stator, a target harmonic current component flowing in a rotary machine. The target harmonic current component is included in a fundamental current component of the phase current. An inducing unit superimposes, on the phase information, a fluctuating signal that changes at an angular velocity identical to an angular velocity of the target harmonic current component, to induce a counteracting harmonic current component in the at least one phase winding. The counteracting harmonic current component counteracts the target harmonic current component.

摘要： A method and system for controlling a vehicle motor are provided. The system includes an inverter that controls the motor to receive a torque command from an external system and output a torque based on the torque command. Additionally, a current command is generated based on the torque command and a operation condition of the motor. A voltage command is generated to be applied to the motor based on the current command and the operation condition of the motor. A pulse width modulation (PWM) command is generated based on the voltage command and the operation condition of the motor. The PWM command is converted to a voltage in a PWM form based on the motor operation condition and is applied to the motor. Then, an unwanted torque output of the motor generated based on a nonlinear characteristic of the motor is added and subtracted to and from the torque command.
