PROBLEM TO BE SOLVED: To provide a control apparatus capable of suitably adjusting interlinkage magnetic flux generated in a coil of an SR motor.SOLUTION: A control apparatus 30 controls a switched reluctance motor by adjusting an output voltage outputted from a power conversion circuit 20 to a coil 22. The control apparatus 30 sets a command voltage of the power conversion circuit 20 on the basis of a torque command value for commanding output torque of the motor and a rotational angle so that interlinkage magnetic flux generated in the coil by applying voltage to inductance L of the coil 22 in a first period of the rotational angle becomes a previously determined prescribed waveform. Further the control apparatus 30 corrects the command voltage on the basis of rotational velocity of the motor, the toque command value and a detection value of a coil current in order to suppress a change in voltage applied to the inductance L generated due to flow of a current into a resistance component R of the coil 22. Then the control apparatus 30 controls the output voltage of the power conversion circuit 20 on the basis of the corrected command voltage. |
