PROBLEM TO BE SOLVED: To provide an active type vibration isolation device and an active type vibration isolation method capable of highly accurately estimating an internal temperature of an actuator.SOLUTION: A computer 206 of an active type vibration isolation device 200 calculates an output average duty ratio DUTaveout used for achieving an operation command value C. The computer 206 calculates a reference average duty ratio DUTaveref achieving the operation command value C when an actuator internal temperature Tacm is a reference temperature Tref based on a point number Np and a command value C being an integer so that the point number Np and the command value C are set to be larger as a rotational period Pv of a driving source 12 becomes longer. The computer 206 calculates the internal temperature Tacm based on deviations of DUTaveout and DUTaveref.SELECTED DRAWING: Figure 19

    【課題】アクチュエータの内部温度を高精度に推定すること等が可能な能動型防振装置及び能動型防振方法を提供する。【解決手段】能動型防振装置200のコンピュータ206は、動作指令値Cを実現するために用いた出力平均デューティ比DUTaveoutを算出する。コンピュータ206は、アクチュエータ内部温度Tacmが基準温度Trefであるときに動作指令値Cを実現する基準平均デューティ比DUTaverefを、駆動源12の回転周期Pvが長くなるほど大きくなるように設定された整数のポイント数Npと指令値Cとに基づいて算出する。コンピュータ206は、DUTaveout及びDUTaverefの偏差に基づいて内部温度Tacmを算出する。【選択図】図19
