Method and system for correcting errors in fueling commands

A system for correcting fueling commands, the system comprising:

• an engine and/or generator including one or more fuel control valves;
• a pressurized fuel supply configured to provide fuel to the engine and/or generator;
• and
• a fuel correction controller in operative communication with the engine and/or generator and the pressurized fuel supply, the fuel correction controller configured to:
• calibrate the engine and/or generator operating in a steady-state mode by determining a plurality of accuracy errors associated with a fueling rate based on a plurality of measurements associated with a lambda sensor;
• determine fueling rate correction data during on-line operation of the engine based on the plurality of accuracy errors from calibrating the engine, wherein the on-line operation of the engine comprises operating the engine in a transient mode at a first period of time and the steady-state mode at a second period of time;
• and
• control the one or more fuel control valves during the on-line operation of the engine using a corrected fueling command, wherein the corrected fueling command is based on the fueling rate correction data.
