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, calculates a correction value Icrt1 according to an internal temperature Tacm of the actuator 210, corrects the operation command value C using the correction value Icrt1, 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 adjusts the correction value Icrt1 at a command value correction unit 254.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に応じた補正値Icrt1を算出し、補正値Icrt1を用いて動作指令値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、指令値補正部254における補正値Icrt1を調整する。【選択図】図3
