Zusammenfassung:	To provide a methane fermentation facility capable of estimating an operating state with a high degree of accuracy and realizing the operating state desired by an operator.SOLUTION: A method for estimating an operating state of a methane fermentation facility includes steps of: expressing a methane fermentation model with a state space model using at least some variables of the methane fermentation model as state variables; obtaining observed values in a methane fermentation facility (100) including a fermenter 140; and sequentially estimating the state variables by applying iterative estimation filters to the state space model using the observed values.SELECTED DRAWING: Figure 1 【課題】メタン発酵設備で、操業状態を高精度に推定可能として、オペレータが希望する操業状態を実現可能とする。【解決手段】メタン発酵モデルの少なくとも一部の変数を状態変数としてメタン発酵モデルを状態空間モデルで表現する工程と、発酵槽１４０を含むメタン発酵設備（１００）にて観測値を得る工程と、前記観測値を用いて前記状態空間モデルに対して逐次推定用フィルタを適用することで前記状態変数を逐次推定する工程と、を含む。【選択図】図１
