Abstract
A system for actively damping a power steering system includes a damping activation module that generates a damping activation signal based on a motor velocity signal, a t-bar torque signal, and a final motor command; a command calculation module that generates a calculated command based on the motor velocity signal and a vehicle speed signal; and a damping calculation module that generates a damping command based on the damping activation signal and the calculated command, the damping command reduces a motor velocity of a motor of the power steering system to mitigate a rack disturbance.
