Abstract:
1. A control apparatus for an electric rotating machine comprising: a prediction section to predict a controlled variable of the electric rotating machine applied with an output voltage of a power conversion circuit for each of prescribed operation states of the power conversion circuit including switching elements each connected to a corresponding one of terminals of the electric rotating machine and on/off-controlled to make and break electrical connection between a positive or a negative terminal of a DC power source and the corresponding one of the terminals of the electric rotating machine; and a manipulation section to manipulate the power conversion circuit to operate in one of the operation states as an actual operation state determined based on the controlled variable predicted by the prediction section, wherein the control apparatus further comprises an average voltage direction calculating section to calculate a direction of an average output voltage vector of the power conversion circuit, and the manipulation section includes a priority setting section to set priority for each of the operation states based on the direction of the average output voltage vector calculated by the average voltage direction calculating section in determining the actual operation state.
