Abstract: A steering control apparatus for a steering system includes a controller. The controller sets a limit value to less than or equal to a steering angle limit value, the limit value being an upper limit of an absolute value of a torque command value, and controls a motor such that a motor torque follows the torque command. When the absolute value of a rotation angle of a rotary shaft exceeds a steering angle threshold, the controller computes a damping control amount such that the damping control amount increases with an increase in an excess of an angular velocity of the rotary shaft over a first upper limit angular velocity. The controller computes the torque command value based on a value obtained by combining the basic command value and the damping control amount such that an absolute value of the basic command value is reduced.

The electronic control unit causes a rotational angle of the reactive force motor to follow the reactive-force-related composite angle command value. The electronic control unit causes a rotational angle of the steering motor to follow the steering-related composite angle command value. The electronic control unit estimates a first disturbance torque.
