A rotating electrical machine control device shifts a control system to synchronous five-pulse control when an operating point crosses a second boundary K22 from a state in which asynchronous pulse-width modulation control is being executed, and shifts the control system to the asynchronous pulse-width modulation control when the operating point crosses a first boundary K21 from a state in which the synchronous five-pulse control is being executed. The first boundary K21 is set such that the number of switching pulses per unit rotational speed by the synchronous five-pulse control immediately before the operating point crosses the first boundary K21 is smaller than the number of the switching pulses per unit rotational speed by the asynchronous pulse-width modulation control immediately after the operating point crosses the first boundary K21.
