A controller controls a steering motor in accordance with a pinion angle command value calculated in response to a steering state. The steering motor produces a driving force to be provided to a steering operation mechanism of a vehicle. The controller calculates a target pinion angle θ* that is a target value for a pinion angle calculated in accordance with the steering state. The controller calculates the pinion angle command value by performing feedback control such that an actual pinion angle corresponds to the target pinion angle θ*. The controller includes a compensation control circuit 63. The compensation control circuit 63 calculates compensation amounts (θ, θ, θ) so as to compensate for an inertia component, a viscosity component, and a spring component of the steering operation mechanism in accordance with the target pinion angle θ*. The compensation amounts are reflected in the pinion angle command value. The compensation control circuit 63 adds the compensation amounts to the target pinion angle θ* so as to calculate the final target pinion angle θ* to be used for the calculation of the pinion angle command value.
