The invention relates to a closed-loop automatic control device and a method of a door opener. An output end of a MCU control chip is connected with an input end of a motor control chip through an A/D conversion chip; an input end of a driving circuit is connected with an output end of the motor control chip; an output end of the driving circuit is connected with an input end of a motor; one end of a motor speed measuring chip is connected with a motor, and the other end is connected to an input end of the MCU control chip through the A/D conversion chip; one end of a current sampling chip is connected with the driving circuit, and the other end is connected to the input end of the MCU control chip through the A/D conversion chip; and the MCU control chip is connected with a sensor through an interface circuit. A method of combining a closed-loop feedback principle with a PWM pulse width modulation signal is used for enabling a door to be decelerated under the wind impact so as to generate excellent wind resistance.
