Abstract
The present invention includes a control amount calculation unit which calculates two or more control amounts each indicating a driving condition of a rotary electric machine on the basis of output current from and a switching state in a power converter; a limitation range-provided command value generation unit which generates limitation range-provided command values relative to command values for the control amounts; and a switching state determination unit which determines a switching state such that each control amount falls within the limitation range of the corresponding limitation range-provided command value. For at least one of the limitation range-provided command values, the limitation range thereof is temporally changed on the basis of the driving condition of the rotary electric machine.
