Provided is a rotating electric machine control system which, in a hybrid system including a pair of rotating electric machines for receiving power supply from a common battery, one rotating electric machine serving as a generator and the other rotating electric machine serving as a motor, ensures protection of an area from the battery to an inverter by preventing an over current from flowing. The rotating electric machine control system comprises a torque restricting means for restricting the output torque of the rotating electric machine, and a battery power sudden change predicting means for predicting a sudden-change state in which the battery power changes suddenly on the basis of at least one of the rate of change of the battery power and the rate of change of the rotational speed of the rotating electric machine. The torque restricting means changes the form of restriction on the output torque in a non-sudden change state in which the battery power does not change suddenly, when the sudden change state is predicted by the battery power sudden change predicting means.
