Abstract
A control apparatus for is a rotating electric machine applied to a control system including a power conversion circuit, a rotating electric machine, and a capacitor. The control apparatus selects two types of active voltage vectors that sandwich a command voltage vector that is applied to a rotating electric machine from a power conversion circuit and have a phase difference of 60 degrees therebetween. The control apparatus selects, of two types of active voltage vectors that sandwich the command voltage vector and have a phase difference of 120 degrees therebetween, one of two types of active voltage vectors that differs from the two types of active voltage vectors selected earlier, based on a driving state of the rotating electric machine. The control apparatus controls the power conversion apparatus to perform switching operations to control the rotating electric machine, based on the selected three types of active voltage vectors.
