PROBLEM TO BE SOLVED: To provide a motor controller including a function for cancelling disturbance by estimating disturbance of a harmonic wave mixed into the input side of a motor and feeding back the estimated disturbance estimation value to the input side and to provide an electric power steering device having the same thereon.SOLUTION: The motor controller, driving a motor taking a current command value as a voltage command value with a current control unit and feeding back a current detection value of the motor to the current command value, includes a disturbance observer which cancels disturbance by estimating disturbance mixed into the input side of the motor and feeding back the estimated disturbance estimation value to the input side.SELECTED DRAWING: Figure 5

    【課題】モータの入力側に混入する高調波の外乱を推定し、推定された外乱推定値を入力側にフィードバックして外乱を相殺する機能を具備したモータ制御装置及びそれを搭載した電動パワーステアリング装置を提供する。【解決手段】電流指令値を電流制御部で電圧指令値としてモータを駆動すると共に、モータの電流検出値が前記電流指令値にフィードバックされているモータ制御装置において、モータの入力側に混入する外乱を推定し、推定された外乱推定値を入力側にフィードバックして外乱を相殺する外乱オブザーバを具備する。【選択図】図5
