Abstract

A control apparatus for an AC rotary machine, including first voltage command calculation means for calculating first voltage commands from current commands, an angular frequency, and constant set values of the AC rotary machine, second voltage command calculation means for calculating second voltage commands on the basis of difference currents between the current commands and current detection values, so that the difference currents may converge into zero, third voltage command calculation means for calculating third voltage commands by adding the first voltage commands and the second voltage commands, voltage application means for applying voltages to the AC rotary machine on the basis of the third voltage commands, and constant measurement means for calculating the constant set values on the basis of the second voltage commands.
