Abstract
A rotary electric machine control system includes a battery electric power calculation unit for calculating battery electric power that is supplied from the battery; a torque limitation unit for limiting an output torque of the rotary electric machine; and a battery electric power abrupt variation estimation unit for estimating that the battery electric power is in an abrupt variation state in which the battery electric power is varying abruptly on the basis of at least one of a variation rate of the battery electric power and a variation rate of a rotational speed of the rotary electric machine.
