<P>PROBLEM TO BE SOLVED: To detect abnormality in a control system regardless of a value of torque relating to a rotary electric machine control system. <P>SOLUTION: The rotary electric machine control system 100 includes a rotary electric machine 300 and an inverter circuit part 200, and switches between over modulation current control mode for current feedback and PWM current control mode at the least. It includes, in each control mode, an offset value calculation circuit part 402 for calculating an offset value of current value for the rotary electric machine 300, an offset abnormality determination threshold value acquiring part 404 for acquiring an offset abnormality determination threshold value set according to torque command value, and a comparison part 406 which compares the calculated offset value with the offset abnormality determination threshold value to determine control abnormality. <P>COPYRIGHT: (C)2010,JPO&INPIT |
