1. A power steering system comprising:

  • a gain module that generates an estimated driver torque; and

    a blending module for determining a blend value, the blend value is based at least in part on a derivative of the estimated driver torque, the blend value determined based on a multiplication of a torque scale factor, a torque gradient scale factor calculated from the derivative of the estimated driver torque, and a velocity error scale factor, and the blend value is applied to a return torque of a handwheel.
