  "textContent": "In a gas turbine control apparatus, a frequency analyzing section (12) analyzes the frequency of at least one pressure oscillation in combustors of a gas turbine and the acceleration oscillation of each of the combustors and outputs a first frequency analysis result as the result of frequency analysis for a plurality of predetermined frequency bands. A control unit (11,21,24,27,30,33,34) controls at least one of a first fuel flow rate of fuel and a first air flow rate of air based on the first frequency analysis result for the plurality of frequency bands. The fuel and the air are supplied to the gas turbine.",
