Portrait action control method and system thereof

The invention relates to the technical field of portrait control and discloses a portrait action control method and a system thereof. Joints of portrait limbs are connected with steering engines and angle sensors. The portrait action control method comprises the steps that S1, the steering engines operate from an initial state to an action state, and the angle sensors obtain a first vibration angle of the steering engines; the steering engines operate from the action state to a keeping state, and the angle sensors obtain a second vibration angle of the steering engines; the steering engines operate from the keeping state to the action state, and the angle sensors obtain a third vibration angle of the steering engines; and the steering engines operate from the action state to the initial state, and the angle sensors obtain a fourth vibration angle of the steering engines; S2, according to the first vibration angle, the second vibration angle, the third vibration angle and the fourth vibration angle, a pluralit
