PROBLEM TO BE SOLVED: To provide gas turbine control method and a device maintaining design performance and an operating state based on ideal fuel flow rate and air flow rate assumed when designing by preventing operation deviated from an operating state that is based on the ideal fuel flow rate and air flow rate assumed by initial design values, in the gas turbine control method designed to automatically search optimal operation conditions using control inputs such as a pilot ratio. SOLUTION: The gas turbine control device comprises a second database that stores load sensitivity, which is the correlation between control inputs such as a fuel flow rate, an air flow rate, a pilot fuel ratio and a top hat fuel ratio in a gas turbine and a load amount of the gas turbine. An amount of load variation for at least one of control inputs of a fuel flow rate and an air flow rate supplied to a combustor is predicted according to the operation conditions obtained by searching using the load sensitivity, regulation is made according to the prediction results, and the regulation results are stored in the second database.
