Pneumatic cylinder systems have the potential to provide fast and reliable motion characteristics with large power output to weight at low cost to benefit ratios. To properly utilize pneumatic cylinder systems in industrial applications (especially in control situations), mechanical engineers must appreciate and understand the dynamic characteristics of these devices. In this paper, the linearized continuous time dynamics of a pneumatic rodless cylinder system are examined. Two transfer functions, based upon the midstroke and off-centre operation conditions respectively, are presented.
