Abstract
A set rotation angle width related to a rotary machine, of which the rotation speed varies cyclically, is converted to a time width required for the rotary machine to rotate by the set rotation angle width from a given rotation angle position. The converted time width is corrected by a correcting coefficient so that the time width is not affected by the rotation variation of the rotary machine. The correcting coefficient is decided based on the rotation angle position and the rotation speed variation of the rotary machine related to the set rotation angle width from the rotation angle position, and by the correcting coefficient, correction is done so that an actual rotation angle width corresponding to the converted time width becomes the set rotation angle width.
