PROBLEM TO BE SOLVED: To provide a motor controller and electrically-driven power steering device having the same, capable of accommodating a malfunction resulting from a harmonic component by accommodating nonlinearity accompanied with a working point change of a motor while suppressing an increase in a required memory amount.SOLUTION: The motor controller, drivingly controlling a motor on the basis of a current command value for the motor, includes a harmonic wave model part for calculating a compensation command value from a current command value using motor information of the motor by a model which has learned characteristics of at least one harmonic wave component of a motor feature amount showing characteristics of the motor, thereby drivingly controlling the motor on the basis of the current command value and the compensation command value.SELECTED DRAWING: Figure 3
