Abstract
Disclosed example flow ratio controllers include: an inlet; an inlet pressure sensor; first and second outlets; first and second flow valves; first and second position sensors; first and second outlet pressure sensors; and control circuitry configured to: control the first flow valve and the second flow valve based on a predetermined flow ratio for the first outlet and the second outlet, an inlet pressure, the first valve position, the second valve position, the first outlet pressure, and the second outlet pressure; determine a rate of change of the inlet pressure based on measurements from the inlet pressure sensor; and based on the inlet pressure and the rate of change of the inlet pressure, control the first flow valve and the second flow valve to maintain the inlet pressure within a predetermined range of a predetermined inlet pressure.
