Control apparatus for rotating electric machine

A control apparatus for a rotating electric machine that is applied to a rotating electric machine system that includes a rotating electric machine that has a multiple-phase winding, a first inverter that is connected to a direct-current power supply and a first end of a winding for each phase, a second inverter that is connected to a second end of the winding for each phase, a high-potential-side connection line that connects a high potential side of the first inverter and a high potential side of the second inverter, and a low-potential-side connection line that connects a low potential side of the first inverter and a low potential side of the second inverter, the control apparatus comprising:

• a parameter acquiring unit that acquires a parameter that has a correlation with a fundamental current that flows to the winding of each phase;
• a storage unit that prestores correspondence information in which the parameter is associated with an amplitude and a phase of a harmonic voltage that is generated in the rotating electric machine;
• and
• a control unit that controls each inverter to suppress the harmonic voltage based on the correspondence information and the acquired parameter.
