Abstract
A control device has a unit for selecting each of states of an inverter applying a voltage to a generator, a unit for predicting a first current of the generator, flowing at a second time elapsed by one control period from a first time, from a detected current and the state of the inverter at the first time, a unit for predicting a second current of the generator at a third time elapsed by one control period from the second time while using the first current as an initial value of the second current, from information indicating one selected state set at the second time, for each selected state, a unit for determining one state corresponding to the second current nearest to instruction, and a unit for setting the inverter in the determined state at the second time to control current of the generator.
