Electric clothes airing machine, electric control system and control method

An electric control system of an electric clothes airing machine comprises a detection module used for detecting ripple waves generated in current of a brush direct current motor when an electric brush of the brush direct current motor is switched between two adjacent commutator segments; the controller is electrically connected to the detection module; wherein the controller is configured to record the position of the clothes airing rod according to the counting numerical value of the ripple waves, and when the brush direct current motor drives the clothes airing rod to move towards the first vertical direction, the counting numerical value is increased according to the number of the ripple waves generated in the current of the brush direct current motor; the brush direct current motor drives the clothes airing rod to move in the second vertical direction opposite to the first vertical direction, and the counting value is reduced according to the number of ripples generated in the current of the brush direct
