Zusammenfassung:	Two inverters provided at respective both ends of open-end windings are appropriately controlled. A rotating electrical machine control device (1) that can control a first inverter (11) and a second inverter (12) by a plurality of control schemes, respectively, the control schemes differing from each other in at least one of a switching pattern and a switching frequency and being independent of each other, has a control mode in which the first inverter (11) and the second inverter (12) are controlled by the same control scheme in a first speed region (VR1) in which the rotational speed of a rotating electrical machine (80), and the first inverter (11) and the second inverter (12) are controlled by different control schemes in a second speed region (VR2) in which the rotational speed of the rotating electrical machine (80) is higher than in the first speed region (VR1).
