Abstract
A dynamo-electric machine control system including a dynamo-electric machine and an inverter that is interposed between a battery and the dynamo-electric machine and that controls a current flowing through the dynamo-electric machine, wherein a rotation speed and an output torque of the dynamo-electric machine are controlled by the inverter, the dynamo-electric machine control system includes a battery power deriving unit that derives a battery power to be supplied from the battery when the dynamo-electric machine is operated at the rotation speed and the output torque; a limit power determining unit that variably determines a limit power, which is a maximum allowable value of the battery power, in accordance with a battery voltage; and a torque limiting unit that limits the torque of the dynamo-electric machine such that the battery power derived by the battery power deriving unit does not exceed the limit power.
