METHOD AND SYSTEM FOR CONTROLLING GAS TURBINE ENGINE

In a control method of a gas turbine engine, an engine controller 4 outputs a combustor power command FD based on an engine condition from an engine condition detector 3. Then, a combustion controller 6 determines each fuel flow rate based on the combustion power command FD. The combustor controller 6 overrides each fuel flow rate for a certain period, to realize smooth stage-process.
