Classification: CPC F  G  B | IPC B  F  G

Claim 9:
10. A system, the system comprising:
a first position sensor;
a second position sensor;
a fuel valve;
a controller coupled to the first position sensor, the second position sensor, and the fuel valve;
wherein a first resistance of a first resistor associated with the first position sensor is measured and based upon the measured first resistance, a first delta curve is selected, the first delta curve describing differences between a nominal fuel valve position and a first measured fuel valve position associated with the first position sensor;
wherein a second resistance of a second resistor associated with the second position sensor is measured and based upon the measured second resistance, a second delta curve is selected, the second delta curve describing differences between the nominal fuel valve position and a second measured fuel valve position associated with the second position sensor;
wherein the controller is configured to:
receive a first fuel valve position (FVP) from the first position sensor, and apply the first FVP to the first delta curve to obtain a first compensated FVP;
receive a second FVP from the second position sensor, and apply the second FVP to the second delta curve to obtain a second compensated FVP;
correlate the first compensated FVP and the second compensated FVP to obtain a final compensated FVP;
apply the final compensated FVP to a desired fuel valve position to obtain a final fuel valve position and apply the final fuel valve position to the fuel valve to control an operation of the fuel valve.
