Abstract:
A rotary electric machine control apparatus controlling drive of a rotary electric machine includes a pre-limit d-axis voltage arithmetic portion calculating a pre-limit d-axis voltage command value; a pre-limit q-axis voltage arithmetic portion calculating a pre-limit q-axis voltage command value; a d-axis limit portion calculating a d-axis voltage command value; and a q-axis limit portion calculating a q-axis voltage command value. When an absolute value of the pre-limit q-axis voltage command value is greater than an absolute value of a second limit value, and an absolute value of a previous q-axis voltage command value is equal to or greater than the absolute value of the second limit value and is equal to or less than an absolute value of a first limit value, the q-axis limit portion determines a previous q-axis voltage command value as the q-axis voltage command value.
