Claim 0:
1. A method for controlling a dual fuel engine system, the method comprising:
determining a gas flow target for an internal combustion engine of the dual fuel engine system, the gas flow target being based on a gas power target of the internal combustion engine, a thermal efficiency estimate of the internal combustion engine, and a lower heating value (LHV) within the internal combustion engine;
adjusting the gas flow target based on at least one of a measured gas temperature or a measured gas injector pressure;
determining at least one base gas injector command based on the adjusted gas flow target, a gas substitution rate estimate, and a gas substitution rate target; and
determining, based on the at least one base gas injector command, a gas injector command for at least one engine bank,
wherein determining the gas flow target comprises dividing the gas power target by the thermal efficiency estimate and the LHV.
