Pressure-control systems: an approach and design with applications for METC valve testing
A system to control the pressure of a volume over a wide pressure range (atmospheric to 1600 psig) with an accuracy of +-15 psi, a stability of +- 0.05 psi up to 100 scfm, and a settling time of less than 2 minutes was developed at the Morgantown Energy Technology Center (METC) for use in the Lockhopper Valve-Testing and Development Project. The pressure-control system, used in four METC test units, was designed using a computer simulation. The simulation uses time-stepped models of the physical elements of the pressure-control loop such as VOLUME, VALVE, ACTUATOR, etc. The model developed was verified by testing the physical system after construction. The system uses one inlet valve and two vent valves controlled by a split signal from a single, three-mode, analog controller. The pressure-control-loop design and the simulation model are described in this report.
