A method of calculating a motor velocity in an electric power steering system comprises receiving a plurality of motor position signals from a motor position sensor of the electronic power steering system, calculating a plurality of angle difference based on the motor position signals prior to performing any filtering operations on the motor position signals, performing a linear regression analysis on the angle differences to predict an angle difference, and calculating a motor velocity based on the predicted angle difference.
