Wind sweeping angle control method and device, air conditioner and storage medium

The invention relates to a wind sweeping angle control method and device, an air conditioner and a storage medium. The wind sweeping angle control method comprises the following steps: acquiring a target pulse angle of a stepping motor; the target pulse angle is a pulse angle enabling the air deflector to reach a preset target; in the process of controlling the stepping motor to work according to the target pulse angle, obtaining a first pulse angle of the stepping motor in an on-load abnormal state; wherein the on-load abnormal state represents that the air deflector does not act. According to the method, a first pulse angle of an asynchronous motor in an on-load abnormal state is corrected to a target pulse angle, a second pulse angle is obtained, the second pulse angle is the total pulse angle which actually enables an air deflector to reach a preset target at the current moment and needs to be executed, and a stepping motor is controlled to work according to the second pulse angle. The deviation of the pu
