Abstract

The invention relates to the technical field of motor driving, and in particular relates to a submicron motion platform and a motion control method thereof. The submicron motion platform comprises linear motors, air floatation guide rails, a sliding block, a grating ruler, a granite bottom plate, an X-direction bottom plate, a Y-direction bottom plate, a Z-direction support and a driving controller; the linear motors comprise an X-direction linear motor, a Y-direction linear motor and a Z-direction linear motor; the air floatation guide rails comprise an X-direction air floatation guide rail,a Y-direction air floatation guide rail and a Z-direction air floatation guide rail. By adopting the structural design of the linear motors, the air floatation guide rails and the sliding block, the stability and the motion control precision of the motion platform are greatly improved; the X-direction bottom plate and the Y-direction bottom plate are respectively arranged between the X-direction air floatation guide rail and the Y-direction air floatation guide rail, so that the movement stability of the X-direction bottom plate and the Y-direction bottom plate is further improved; due to thedesign of the X-direction linear motor, the Y-direction linear motor and the Z-direction linear motor, precise motion control in the X dimension, the Y dimension and the Z dimension is guaranteed.
