INTELLIGENT CONTROL METHOD WITH VARIABLE THRESHOLDS BASED ON VIBRATION READINGS

摘要

The present invention describes a method for controlling an engine vibration of a gas turbine engine (110). The engine vibration of the gas turbine engine (110) is measured. The measured engine vibration is compared with a threshold value of a nominal engine vibration. A fuel supply parameter of a fuel supply to a combustion chamber (111) of the gas turbine engine (110) is controlled for controlling combustion dynamics of a combustion flame (112) within the combustion chamber (111). The engine vibration of the gas turbine engine (110) is indicative of the combustion dynamics of the combustion flame (112), so that the fuel supply is adjusted for controlling the combustion dynamics if the measured engine vibration exceeds the threshold value of the nominal engine vibration.
