A method of controlling a power steering system is provided. The method generates a base torque command based on a hand wheel torque signal without altering the hand wheel torque signal at a range of relatively low frequencies. The method generates a motor inertia compensation command based on a motor inertia of a motor of the power steering system. The method generates an assist torque command based on the base torque command and the motor inertia compensation command. The method operates a motor of the power steering system to generate a torque based on the assist torque command.
