Abstract: At least one embodiment of the present disclosure provides an electric booster brake apparatus including an electric booster unit, an electronic stability control (ESC) operating unit, and an electric-booster control unit. The electric booster unit has a motor, and a motor piston and a master cylinder and pressurizes the master cylinder by adjusting a displacement of the motor piston. The ESC operating unit includes a pressure sensor measuring pressure in the master cylinder and calculates a required braking pressure. The electric-booster control unit controls the position of the motor piston. The electric-booster control unit includes a feedforward control unit for converting the value of the required braking pressure into a motor piston displacement, and a feedback control unit for calculating a compensation displacement of the motor piston based on a difference between the value of the required braking pressure and the value of the pressure in the master cylinder.
