Abstract
A control system for a power steering system is provided. The control system includes a scaling module for calculating a scale factor based on a wheel frequency. The control system also includes a command module that evaluates a wheel disturbance based on a wheel speed and that determines a wheel disturbance cancel amount based on the wheel speed. The command module generates an assist command to the power steering system based on the wheel disturbance cancel amount and the scale factor.
