PROBLEM TO BE SOLVED: To inhibit the elevation of the exhaust gas temperature in the stopping of a gas turbine and to prevent each equipment of an exhaust system from receiving the excess heat hysteresis. SOLUTION: An intake controller comprises a first exhaust gas temperature set value computing unit 22 for calculating a set value for the starting and the ordinary operation of a gas turbine and a second exhaust gas temperature set value computing unit 28 for calculating a set value for the stopping. A compressor discharge pressure signal (a) is inputted to both of the set value computing units 22, 28, and the exhaust gas temperature set values are respectively determined on the basis of the included functions. The exhaust gas temperature set value signals (b, g) are inputted to a switching unit 29. The switching unit 29 outputs the exhaust gas temperature set value signal (b) when a gas turbine stop signal (h) is not inputted, and outputs the exhaust gas temperature set value signal (g) for the stopping, when the gas turbine stop signal (h) is given.
