Development of discrete pneumatic pressure regulator and researching of its characteristics

Abstract


In the paper, software for digital control of gas pressure in a vessel is developed to increase process quality and accuracy. Operating principal is based on stepped variation of a throttle area at the vessel output (or/and input) using pulse code modulation. The control device is made as set of parallel on-off valves. Flow areas of the valves can be presented by binary dependencies of the smallest cross-section or by the Fibonacci series. The number of valves depends on control process accuracy. Simulation results show a good correlation with experimentally obtained data proving efficiency of the proposed control strategy to providing high accuracy and proper quality of transients.
