Abstract
A control device has a unit for selecting each of controlled voltages outputted from an inverter to a generator, a unit for judging a polarity of a current flowing through the generator, a unit for predicting a current of the generator from each selected voltage to be outputted from the inverter in the succeeding period, while performing the prediction based on the current polarity each time the selected voltage differs from the voltage already outputted from the inverter in the present period, a unit for determining one voltage corresponding to one predicted current nearest to an instructed current among the predicted currents, and a unit for controlling the generator by controlling the inverter to change the voltage already outputted from the inverter to the determined voltage and to apply the determined voltage to the generator in the succeeding period.
