The invention relates to the technical field of engineering machinery, and particularly discloses a rotation system control method, a rotation system and an engineering vehicle, the rotation system control method comprises the following steps: S10, recording the real-time state of the rotation system, the real-time state comprising an acceleration state and a deceleration state; s20, whether the rotation system is in the state switching moment between the acceleration state and the deceleration state or not is judged, if yes, S30 is executed, and if not, S10 is executed; s30, the real-time actual torque and the real-time target torque of the rotation system are recorded; s40, according to the real-time actual torque and the real-time target torque, whether the rotation system is at the torque switching moment or not is judged, if yes, S50 is executed, and if not, S30 is executed; and S50, the change of the torque T of the rotary system along with time t tends to 0, T = f (t), and t is greater than or equal to
