Claim 9:
10. An inference apparatus for inferring a length of a current control period and a length of a magnetic-flux control period for the rotary machine control apparatus according to claim 1, the length of the current control period and the length of the magnetic-flux control period enabling at least one of reduction of an amount of increase in DC bus voltage in the power converter, reduction of a pulsation width of the DC bus voltage, reduction of a pulsation width of frequency of a magnetic flux vector in the rotary machine, and reduction of a pulsation width of an effective current value of an electric current flowing through the rotary machine, the inference apparatus comprising:
an inference data acquirer to acquire a frequency estimation value of the magnetic flux vector, and an effective current value obtained from the current detection value; and
an inference calculator to infer the length of the current control period and the length of the magnetic-flux control period by inputting the frequency estimation value and the effective current value to a learned model for inferring the length of the current control period and the length of the magnetic-flux control period from the frequency estimation value and the effective current value.
