Abstract
In a control apparatus for a rotary electric machine, a first manipulation unit manipulates, as control for a predetermined first region with respect to the controlled variable, a voltage phase of a voltage vector applied to an armature winding while controlling a field current to cause a deviation between an amplitude of an induced voltage and an amplitude of a predetermined voltage to be equal to or smaller than a predetermined value, the induced voltage being generated in the armature winding based on rotation of the rotor, the predetermined voltage being applied to the armature winding; A second manipulation unit that manipulates, as control for a second region that is larger than the first region, the field current such that the controlled variable is controlled to the target value.
