Exemplary embodiments of the present invention relate to a friction compensation logic of MDPS and a friction compensation method using the same. The friction compensation logic of MDPS in accordance with an embodiment of the present invention includes: a signal processor configured to extract only a signal having a limited range from column torque signals input from a column torque; a friction compensation sign calculator configured to determine a friction compensation sign by integrating the column torque signal extracted by the signal processor and calculating the friction compensation sign by limiting the integrated value to a set value; and a friction compensation torque calculator configured to calculate a friction compensation torque by reflecting a friction compensation amount to a value calculated by the friction compensation sign calculator.
