The invention discloses an EPS sliding compensation control system which comprises a data acquisition module, a sliding state recognition module, a sliding torque calculation module and an EPS motor. The data acquisition module is used for acquiring a current hand torque mtbt, a motor torque mmot, a vehicle speed vveh and a motor RPS rotating speed vrps; the sliding state recognition module judges whether the current transmission belt is in a sliding state or not according to the obtained current hand torque mtbt, the motor torque mmot, the vehicle speed vveh and the motor RPS rotating speed vrps; the sliding torque calculation module is used for calculating motor compensation torque when the transmission belt is in a sliding state; and the EPS motor performs compensation according to the motor compensation torque output by the sliding torque calculation module. Normal steering control can be achieved under the EPS transmission belt sliding working condition.
