To provide an active vibration controller capable of highly accurately estimating an internal temperature of an actuator.SOLUTION: An ACM-ECU 206 calculates an operation command value C of an actuator 210 from vibration control of an engine 12, corrects the operation command value C according to an internal temperature Tacm of the actuator 210, and estimates the internal temperature Tacm on the basis of an average duty ratio DUTave as an average of voltage duty ratios DUT of a section to be calculated Ztar. Also the ACM-ECU 206 determines whether to execute correction of the operation command value C.SELECTED DRAWING: Figure 3

    【課題】アクチュエータの内部温度を高精度に推定可能な能動型防振装置を提供する。【解決手段】ACM−ECU206は、エンジン12の振動情報からアクチュエータ210の動作指令値Cを算出し、アクチュエータ210の内部温度Tacmに応じて動作指令値Cを補正し、算出対象区間Ztarの電圧デューティ比DUTの平均としての平均デューティ比DUTaveに基づいて内部温度Tacmを推定する。また、ACM−ECU206は、動作指令値Cの補正の実行要否を判断する。【選択図】図3
