Summary:To perform comparison with higher accuracy even when a difference in a time axis direction occurs between an object signal and a comparison condition.SOLUTION: A control unit comprises: an acquisition unit that acquires time-series signals output from an apparatus; a comparison condition storage unit that stores information indicating the temporal change of a predetermined comparison condition; an area determination unit that determines, from the signals acquired by the acquisition unit, an object area that is an area satisfying a predetermined condition indicating that a change in value is stable; and a comparison unit that performs comparison with the comparison condition by using the signal of the object area determined by the area determination unit.SELECTED DRAWING: Figure 1 【課題】対象信号と比較条件とに時間軸方向のずれが生じていた場合であっても、より高い精度で比較を行うこと。【解決手段】機器から出力される時系列の信号を取得する取得部と、予め定められた比較条件の時間変化を示す情報を記憶する比較条件記憶部と、前記取得部によって取得された前記信号のうち、値の変化が安定していることを示す所定の条件を満たす領域である対象領域を決定する領域決定部と、前記領域決定部によって決定された前記対象領域の信号を用いて、前記比較条件との比較を行う比較部と、を備える制御装置である。【選択図】図１
