A modelling study on pneumatic cylinder actuator systems is carried out based on the standard orifice theory. The pneumatic cylinder actuators are modelled as a cascade connection of two nonlinear subsystems affine in the control input. The model validation has been conducted by comparing open-loop system dynamic responses obtained through simulation and experiments. Finally, a class of robust servo control strategy is proposed, which guarantees the profile following precision. An example is included to demonstrate the servo control design procedure
