<P>PROBLEM TO BE SOLVED: To suppress current overshoots in switching from a rectangular wave voltage phase control mode into an overmodulated current control mode, in a rotating electrical machine control system. <P>SOLUTION: A controller 30 for rotating electrical machines 18 and 20 includes an overmodulated current control module 34; a rectangular wave voltage phase control module 36; a current deviation determining module 40, which determines whether a current deviation in mode switch-over from the rectangular wave voltage phase control mode to the overmodulated current control mode exceeds a preset threshold deviation; and a control-in-switch-over module 42, which executes current feedback control, under normal conditions, when the determination is negative and performs current feedback control within a specified current deviation change rate preset as to a temporal change of the current deviation or below, when the determination is affirmative. <P>COPYRIGHT: (C)2010,JPO&INPIT |
