In a control device for an electric power steering system for controlling a motor on the basis of an auxiliary steering command value calculated from a steering torque generated in a steering shaft and a vehicle speed, and a current detection value of the motor that applies an auxiliary steering force to a steering mechanism, the device comprises a damping compensation unit that calculates a basic damping compensation value on the basis of a steering speed and adjusts the basic damping compensation value on the basis of an SAT estimated value and the steering speed, wherein an adjusted damping compensated value that is adjusted in the damping compensation unit is added to the auxiliary steering command value.
