To provide a filter device for enabling a control object to output a desired output signal without changing a controller.SOLUTION: A filter device includes: an input/output signal acquisition unit for acquiring an input signal inputted to a control object, and acquiring an output signal outputted from the control object in accordance with the input of the input signal; a transfer function calculation unit for updating a parameter of a transfer function of a mounted controller controlling the control object by data drive control based on the input signal and the output signal, and calculating a transfer function of a virtual controller; and a reference signal conversion unit for causing the control object to convert an unupdated reference signal to be inputted to a closed loop system including the control object and the mounted controller into an updated reference signal for outputting a target output signal or an approximate target output signal more approximate to the target output signal than to the output signal by using a transfer function of the control object, the transfer function of the mounted controller and the transfer function of the virtual controller.SELECTED DRAWING: Figure 1 【課題】制御器を変更すること無く、制御対象に所望の出力信号を出力させることができるフィルタ装置を提供する。【解決手段】フィルタ装置は、制御対象に入力される入力信号を取得し、前記入力信号の入力に応じて前記制御対象から出力される出力信号を取得する入出力信号取得部と、前記制御対象を制御している実装済制御器の伝達関数のパラメータを前記入力信号及び前記出力信号に基づくデータ駆動制御により更新して仮想制御器の伝達関数を演算する伝達関数演算部と、前記制御対象の伝達関数、前記実装済制御器の伝達関数及び前記仮想制御器の伝達関数を使用して前記制御対象及び前記実装済制御器を含む閉ループ系に入力される更新前参照信号を前記制御対象に目標出力信号又は前記出力信号よりも前記目標出力信号に近似している近似目標出力信号を出力させる更新後参照信号に変換する参照信号変換部と、を備える。【選択図】図１
