Abstract
A fuel metering system for a combustion section of a turbo machine is provided. The turbo machine includes a main fuel line configured to provide a flow of fuel and a zone fuel line split from the main fuel line through which at least a portion of the flow of fuel is provided. A fuel valve is disposed at the zone fuel line and is configured to obtain and receive a present fuel valve area value and a present valve position value. A first pressure sensor is disposed upstream of the fuel valve, in which the first pressure sensor is configured to obtain a first pressure value. A second pressure sensor is disposed downstream of the fuel valve, in which the second pressure sensor is configured to obtain a second pressure value. A flow meter is disposed downstream of the fuel valve. A controller is configured to perform operations, in which the operations include determining a demanded fuel valve actuator position based at least on an estimated fuel valve actuator position and a demanded fuel flow; comparing the demanded fuel flow and a present fuel flow; determining an actual fuel valve actuator position based at least on the demanded fuel valve actuator position and the compared demande…
