The invention discloses an acceleration compensating control method and device for a lifter. The lifter comprises a carrier for bearing a carried object, wherein a movable bottom plate is arranged inthe carried object; and the movable bottom plate is used for supporting the carried object, and can slide up and down relative to the carried object. The acceleration compensating control method for the lifter comprises the following steps of: detecting an acceleration size and an acceleration direction of the carried object; when acceleration of the carried object is zero, enabling the movable bottom plate to be in a still state relative to the carried object; and when acceleration of the carried object is not zero, enabling the movable bottom plate to accelerate and slide, synchronously generating reverse acceleration reverse to the acceleration direction of the carried object by following the carried object. The lifter adopting the acceleration compensating control method for the liftercan reduce acceleration amount, relative to a body, of blood in a passenger at a starting moment and a braking moment, effectively improves taking comfort of the lifter, and opens space for accelerating the lifter.
