The invention discloses a control method, system and device for a rotor blade of a variable sweepback wing, and relates to the field of rotor blades. The method comprises the following steps: acquiring azimuth angles of first and second paddles; judging whether the azimuth angles of the first blade and the second blade are not within a preset range or not to obtain a first judgment result; if the first judgment result is yes, returning to the previous step; if the first judgment result is no, the sweepback device of the paddle corresponding to the azimuth angle set in the preset range is a to-be-adjusted sweepback device, and the resistance value of the to-be-adjusted sweepback device is obtained; judging whether the resistance value is greater than a preset resistance threshold value or not to obtain a second judgment result; if the second judgment result is yes, the blade tip speed and the forward flying speed generated by rotation of the to-be-adjusted sweepback device are obtained, and the sweepback control angle is calculated; performing sweepback control on the to-be-adjusted sweepback device according to the sweepback control angle; and returning to obtain the resistance value of the to-be-adjusted sweepback device until the azimuth angle is not within the preset range, and performing sweepback on the local high-speed region to realize noise reduction of the high-speed pulse noise.
