Abstract:
1. A computer-implemented method, comprising: determining a first characterization of a first fluid regulator flow relative to a control signal for the fluid regulator, the characterization of the first fluid regulator flow based at least in part on operation of the fluid regulator in a standardized operating environment; receiving characteristics of a projected operational environment for the fluid regulator; generating a second characterization of a second fluid regulator flow of the fluid regulator relative to the control signal based at least in part on the first characterization and the received characteristics of the projected operational environment; and linearizing a fluid regulator flow gain of the fluid regulator relative to the control signal while the fluid regulator operates in an operational environment modeled by the projected operation environment, wherein linearizing of the flow gain relative to the control signal is based on the generated second characterization, wherein the second characterization is determined according to: wherein, for a liquid, x is the first characterization and γ is equal to a pressure drop across the fluid regulator at a max flow rate divided by a pressure drop across the fluid regulator at a min flow rate, and wherein, for a gas, x is the first characterization and γ is determined according to wherein dPratio is equal to a pressure drop across the fluid regulator at a max flow rate divided by a pressure drop across the fluid regulator at a min flow rate and P
