VECTOR CONTROL DEVICE FOR ELECTRIC MOTOR, ELECTRIC MOTOR, VEHICLE DRIVE SYSTEM, AND VECTOR CONTROL METHOD FOR ELECTRIC MOTOR |
摘要 |
A vector control device that controls an electric power converter 2 that converts DC power to AC power and supplies the AC power to an AC electric motor 1, includes a vector control unit 3 computing an output voltage output from the electric power converter 2 according to vector control based on torque command and flux command and generating a PWM signal for controlling the electric power converter based on the output voltage, a first flux-command generation unit 11a generating a flux command for asynchronous PWM mode, and a second flux-command generation unit 11b generating a flux command for synchronous PWM mode. When an output frequency of the electric power converter 2 is lower than predetermined value, a flux command generated by the first flux-command generation unit 11a is input to the vector control unit 3, and when the output frequency of the electric power converter 2 is equal to or higher than predetermined value, a flux command generated by the second flux-command generation unit 11b is input to the vector control unit 3. |
