This paper presents a physical dynamic modelling of a dual-drive gantry stage which takes into account the rigid body motion and the first flexion mode. It is used to study the influence of the mechanical coupling between the two parallel axes on the global positioning performances. Indeed, dual-drive mechanisms are commonly controlled with two independent and symmetrical position controllers while the mechanical structure is not symmetrical. This control strategy leads to an imperfect… CONTINUE READING
