According to one embodiment of the present invention, a regenerative braking system comprises a transportation means and an induction motor, wherein a battery is charged when the induction motor is driven with a negative torque. The regenerative braking system comprises: a disturbance observer configured to receive a following damper (B_em) to provide a following motor torque (T_em) of the induction motor in accordance with the following damper; a continuous control set-model predictive torque control (CCS-MPTC) configured to control the induction motor to allow the induction motor to operate while following the following motor torque; and a Q filter, wherein the B_em is set so that a rotation angle speed W_m of a driving unit of the transportation means does not have a negative value. The purpose of the present invention is to provide a regenerative braking system having good battery charging efficiency and a safe following damper value.
