<P>PROBLEM TO BE SOLVED: To provide a control device of an AC rotary electric machine capable of improving follow-up performance with respect to a current command even when a torque command includes a periodic torque vibration, and preventing a phase of an output voltage waveform of a rectangular wave from changing rapidly when rectangular wave control execution is started. <P>SOLUTION: A current feedback control unit calculates a two-phase voltage command on the basis of at least an output value of an operation which uses a harmonic model having a periodic function characteristic of a torque vibration frequency. When rectangular wave control execution is started, the current feedback control unit performs attenuation processing which gradually changes the output value of the operation which uses the harmonic model so that the output value becomes zero within the period set according to a torque vibration period. <P>COPYRIGHT: (C)2013,JPO&INPIT |
