Abstract:
1. A method, comprising executing computer executable instructions by one or more processors for control of a gas flow control valve, the method further comprising: receiving a desired fuel command and an inlet pressure parameter; determining a choked valve flow factor and an unchoked valve flow factor, both the choked valve flow factor and the unchoked valve flow factor based at least in part on the inlet pressure parameter; determining a gas flow gain based at least in part on either the choked valve flow factor and the unchoked valve flow factor, wherein determining the gas flow gain further comprises inverting the product of the choked valve flow factor and an unchoked multiplier; determining a valve flow coefficient based at least in part on the desired fuel command and the gas flow gain; and controlling the gas flow control valve based at least in part on the valve flow coefficient.
