CONTROL APPARATUS

摘要

The present invention addresses the problem of providing, as a control apparatus relating to a rotational solid rotated by a four-stroke engine, a control apparatus having a high degree of freedom in selecting the apparatus to which the control apparatus can be applied. The control apparatus comprises a rotational speed acquisition unit configured so as to obtain the rotational speed of a rotational solid rotated by a four-stroke engine, and an undulation detection unit configured so as to detect, on the basis of the rotational speed obtained by the rotational speed acquisition unit, periodic undulation which is included in rotational fluctuation of the four-stroke engine and which has an angle period longer than a crank angle equivalent to four strokes.
