PROBLEM TO BE SOLVED: To provide a control device for a gas turbine engine suppressing fluctuation of engine rotation speed by accurately control total of fuel supplied to the gas turbine engine to a target value when combustion style is changed over between premixed combustion and diffusing combustion. SOLUTION: This device is provided with a first valve regulating fuel used for premixed combustion and a second valve regulating fuel used for diffusing combustion. When combustion style is changed over from one to another, a valve corresponding to another combustion style of the first valve and the second valve is opened to supply fuel necessary for executing another combustion style, and opening of the valve corresponding to one combustion style is gradually reduced and opening of the valve corresponding to another combustion style is gradually increased with keeping total of premixed fuel flow rate Gfpre and diffusing fuel flow rate Gfdiff after a predetermined period TIME-pre-stg elapses from open of the valve corresponding to another combustion style.
