Abstract:
A control apparatus for a multi-phase rotating electric machine includes at least one electric power converter, a command value calculator and an input voltage determiner. The at least one electric power converter converts DC power into multi-phase AC power and supplies the multi-phase AC power to the rotating electric machine. The command value calculator calculates command values for operating the at least one electric power converter. The input voltage determiner determines whether an input voltage of the at least one electric power converter is within a normal operation range. When the input voltage is determined by the input voltage determiner to be outside the normal operation range, the control apparatus switches control to ignore voltage change or current change caused by the reverse input of an external force to the rotating electric machine from a load side or suppress control fluctuation caused by the reverse input of the external force.

Claim (Index 6):
The control apparatus as set forth in  claim 4 , wherein the rotating electric machine includes a first three-phase coil set and a second three-phase coil set,\n the at least one electric power converter comprises a first electric power converter configured to output first alternating current to the first three-phase coil set and a second electric power converter configured to output second alternating current to the second three-phase coil set, the first alternating current and the second alternating current being different in phase from each other by (30\u00b160\u00d7n)\u00b0 in electrical angle, where n is an integer, the input voltage of the at least one electric power converter comprises a first input voltage and a second input voltage, the first input voltage being a voltage between a high-potential line and a low-potential line of the first electric power converter, the second input voltage being a voltage between a high-potential line and a low-potential line of the second electric power converter, the command value calculator comprises: a current sum controller that calculates, by P 1  control, a sum of a first voltage command value for the first electric power converter and a second voltage command value for the second electric power converter so as to make a current-sum deviation approach 0, the current-sum deviation being a deviation between a sum of first and second current command values and a sum of first and second current feedback values, the first and second current command values being respectively a command value for the first alternating current and a command value for the second alternating current, the first and second current feedback values being respectively a feedback value of the first alternating current and a feedback value of the second alternating current; and a current difference controller that calculates, by PI control, a difference between the first and second voltage command values so as to make a current-difference deviation approach 0, the current-difference deviation being a deviation between a difference between the first and second current command values and a difference between the first and second current feedback values, when at least one of the first and second input voltages is determined by the input voltage determiner to be outside the normal operation range, the command value calculator reduces proportional and integral gains of both the current sum controller and the current difference controller or the proportional and integral gains of only the current difference controller to become less than during normal operation of the rotating electric machine.
