A rotation angle estimation unit calculates a rotation angle of a rotor from a d-axis current and a q-axis current that flow into a motor of an onboard fluid machine and from a d-axis voltage command value and a q-axis voltage command value. A correction unit of an inverter device applies a pulse voltage to the motor when the motor is in a stopped state. Further, the correction unit corrects a parameter for control of the motor in accordance with a comparison result of the d-axis current and the q-axis current, which flow into the motor when the pulse voltage is applied.
