Abstract
In a control unit that controls a control amount of a rotary device by controlling on and off states of switching elements of a power converting circuit, a relative rate predicting section temporally sets operation states of the power converting circuit and predicts a relative rate of a control amount according to each of the temporally set operation states relative to a command value thereof. Each of the operation states is indicated by a voltage vector defined by the on and off states of the switching elements. A determining section determines an operation state of the power converting circuit based on the relative rate predicted by the relative rate predicting section. An operating section operates the power converting circuit to the operation state determined by the determining section.
