<P>PROBLEM TO BE SOLVED: To restrain a difference from arising in voltage amplitude at switching from a sine wave control mode to an over-modulation control mode in a rotary electric machine control system. <P>SOLUTION: The rotary electric machine control system 10 includes a rotary electric machine 12, a power circuit 20 which is connected to this, and a control unit 40 which controls the operation of these components as a whole. The voltage amplitude correcting module 50 of the control unit 40 has a function of performing the correction of voltage amplitude similar to the correction of the voltage amplitude executed in the over-modulation control mode, between the timing that the user wants to switch the mode from the sine wave control mode to the over-modulation control mode based on the operational situation of the rotary electric machine and the timing that switching into the over-modulation control mode takes place actually. <P>COPYRIGHT: (C)2010,JPO&INPIT |
