Discrete-time Simulation of Air-flow Cut-off in Pressure-controlled Valves

چکیده
In this research, the behaviour of the differential equation governing volume flow through a pressure-controlled valve is examined with particular attention given to the rather troublesome transition between an open and closed valve. A closed-form solution for the time evolution of volume flow is given and used to derive an update for the volume flow. The result is a smooth, nearly alias free transition between the two states. The form of the update is similar to that of a leaky valve where the leakage decreases as the volume flow decreases.
