CONTROLLER FOR ELECTRIC MOTOR SYSTEM |
摘要 |
A controller for an electric motor system is provided. The electric motor system includes a DC power supply, a power converter, a smoothing capacitor, a three-phase AC motor, and a current sensor. The controller includes an electronic control unit. The electronic control unit is configured to control the power converter such that an inter-terminal voltage of the smoothing capacitor matches a first reference value. The first reference value is a value which is determined as the inter-terminal voltage of the smoothing capacitor when a phase current is equal to a second reference value. The electronic control unit is configured to correct a detection value of the current sensor so as to decrease a difference between the detection value and the second reference value when the inter-terminal voltage matches the first reference value and the detection value does not match the second reference value. |
