In a control system for a gas turbine engine, a degradation level of the gas turbine engine is estimated according to a deviation of an output of an internal temperature sensor when the engine is producing a target output at a target rotational speed from a prescribed reference temperature, and a correction value for correcting the engine operation map is computed according to the degradation level of the gas turbine engine. Thereby, even when the degradation of the engine has progressed to a certain extent typically owing to the aging of various component parts, the engine operation map can be corrected in such a manner that the level of fuel supply is optimally selected and the acceleration, efficiency and other items of performance of the engine can be improved.
