Abstract

A method for controlling a motor in an electrical power steering system is provided. The method generates a damping torque command for reducing an undesired torque to be generated by the motor. The method generates an assist torque command that specifies a desired torque to be generated by the motor. The method determines whether to send the damping torque command to the motor as a function of a hand wheel velocity and a hand wheel angle. The method combines the assist torque command and the damping torque command to send to the motor when it is determined that the damping torque command is to be sent to the motor.
