  • Patent number: 9531313
    Abstract: In a control apparatus, an interference-reduction current calculator calculates, as an interference reduction current, a component of a current vector in a coordinate axis in a rotating coordinate system defined with respect to a rotor of the rotary machine. The current vector flows in the rotary machine, and the coordinate axis serves as an interference reduction coordinate axis in which the component of the current vector has reduced interference from change of the phase of the output voltage vector. An amplitude setter sets, as a manipulated variable for feedback controlling the interference reduction current to a command current value based on a command value for a controlled variable, one of: an amplitude of the output voltage vector, and an amplitude parameter indicative of a component of the output voltage vector. The component of the output voltage vector depends on the amplitude of the output voltage vector.
