Claim 0:
1. A rotating electrical machine control system for a vehicle's drive power source whose control target is an alternating-current rotating electrical machine including M coil sets (M is a natural number greater than or equal to 2) of N phases (N is a natural number), the rotating electrical machine control system comprising:
M inverters each including a plurality of switching elements and connected to a direct-current power supply and one of the coil sets to convert electric power between a direct current and alternating currents of N phases;
current sensors provided for each phase flowing through the coil sets; and
an inverter control device that generates switching control signals for controlling the plurality of switching elements, to control the inverters,
wherein the inverter control device performs current feedback control of the rotating electrical machine using all detection values for each of N phases obtained by the current sensors, to generate the switching control signals common to the M inverters, wherein
the inverter control device obtains the actual current flowing through the rotating electric machine by averaging the detected values of the current sensors of M sets at the same timing, sets the current flowing in one of said coil sets as a target current, and performs current feedback control of said rotating electric machine based on the deviation between said actual current and said target current, to generate said switching control signals common to the M inverters, or
the inverter control device obtains the actual current flowing through the rotating electric machine by adding up the detected values of M sets of current sensors at the same timing, sets the current flowing in the M sets of coils as the target current, and performs current feedback control of the rotating electric machine based on the deviation between the actual current and the target current, to generates said switching control signals common to the M inverters.
