description The invention provides a control system of a presser foot lifting mechanism, a control method of the control system and a sewing machine. The control system of the presser foot lifting mechanism comprises a control part, a driving part, a detection assembly and the presser foot lifting mechanism. The detection assembly comprises a signal sending piece and three signal receiving pieces, and the sending end of the signal sending piece faces the area where the three signal receiving pieces are located; and the three signal receiving pieces are respectively close to the starting end, the middle section and the terminating end of the feed dog. The control piece controls the driving piece according to the receiving information received by the signal sending piece, then the presser foot lifting mechanism is driven to ascend and descend, and noise generated by collision between the presser foot and the feed dog is reduced. According to the control method of the presser foot lifting mechanism, the receiving informatio
