Zusammenfassung:	To prevent an advance control signal based on a previous load change from being a disturbance to realize stable operation when performing next load change after a changing load reaches a target load value.SOLUTION: A boiler controller comprises an advance control signal generation unit, and an advance control signal adjustment unit. The advance control signal generation unit generates an advance control signal for a boiler based on change of a load of the boiler. The advance control signal adjustment unit adjusts the advance control signal so that the advance control signal becomes zero when the load reaches a target load value.SELECTED DRAWING: Figure 3 【課題】変化する負荷が目標負荷値に到達した後に、次の負荷変化を行う際に、前の負荷変化に基づく先行制御信号が外乱となることを防止することで、安定的な運転を実現する。【解決手段】ボイラ制御装置は、先行制御信号生成部と、先行制御信号調整部とを備える。先行制御信号生成部は、ボイラの負荷の変化に基づいてボイラに対する先行制御信号を生成する。先行制御信号調整部は、負荷が目標負荷値に到達した際に先行制御信号がゼロになるように先行制御信号を調整する。【選択図】図３
