In pneumatic pressure control applications the influence of tubes that connect the valve
with the control volume is mainly neglected. This can lead to stability and robustness
issues and limit either control performance or tube length. Modeling and considering
tube behavior in controller design procedure allows longer tubes while maintaining the
required performance and robustness properties without need for manual tuning. The
author’s previously published Simplified Fluid Transmission Line Model and the proposed
model-based controller design enable the specification of a desired pressure trajectory in
the control volume while the pressure sensor is mounted directly at the valve. Thus wiring
effort is reduced as well as cost and the chance of cable break or sensor disturbance. In
order to validate the simulated results the proposed control scheme is implemented on a
real-time system and compared to a state-of-the-art pressure regulating valve.
