PURPOSE: An optimal combustion controller of a gas turbine is provided to properly respond to frequencies changed according to dispatch output demand and to increase combustion efficiency by optimally supplying air flow and fuel flow. CONSTITUTION: An optimal combustion controller comprises an output setting part (100), a maximum power setting part (200), a frequency correction part (300), an addition part (400), and a fuel flow adjusting part (500). The output setting part receives automatic dispatch signals and outputs the first output setting value of a generator. The maximum power setting part adds the output setting values of a net rating generator and correction values according to the variation of ambient temperature so that the maximum output setting value of the generator can be outputted. The frequency correction part outputs frequency correction values within the maximum output setting value of the generator and the preset minimum output setting value of the generator. The addition part adds the first output setting value of the generator and the frequency correction values so that the second output setting value of the generator can be outputted. The fuel flow adjusting part outputs fuel control valve adjusting signals by proportionally integrating proportional integral values and fuel flow with a second proportionally integrator.
