Abstract
A steering control device for controlling a rotation angle of a motor that drives a steering mechanism according to a rotation angle of a steering wheel, includes a torque controller to control torque of the motor with the rotation angle of the steering wheel as a command value, and a phase advance processor to perform feedback control on the torque of the motor with at least one of the rotation angle and angular velocity of the motor as a command value, and advance a phase of a signal waveform to be fed back for a partial frequency range that includes a resonance frequency of the motor and the steering mechanism in an entire frequency range.
