A rotating electrical machine control system (100) whose control target is an alternating-current rotating electrical machine (80) including M coil sets (8) includes M inverters (50) each including a plurality of switching elements (5) and connected to a direct-current power supply (41) and one of the coil sets (8) to convert electric power between a direct current and alternating currents of N phases; M current sensors (6) each provided for each coil set (8) to detect an alternating current of each phase flowing through the coil set (8); and an inverter control device (30) that generates switching control signals (S) for controlling the plurality of switching elements (5). The inverter control device (30) performs current feedback control of the rotating electrical machine (80) using all detection values for each of N phases obtained by the M current sensors (6), to generate the switching control signals (S) common to the M inverters (50).
