Abstract

PURPOSE: To perform quicker control in a device porvided with the second stage nozzle between high pressure and low pressure turbines, by controlling the second stage nozzle with a fuel flow control signal of a gas turbine as a preceding value.
CONSTITUTION: A gas turbine controller is constituted so as to operate a start control 1, exhaust gas temperatuer control 3 and speed control 5, and a fuel flow regulating valve 7 is controlled by a fuel control signal through a low value selective circuit 6. Further for control of the second stage nozzle 13, a speed signal, on the basis of a signal of a speed detector 21 additionally provided to a high pressure turbine shaft 20, and output of a speed setter 19 are collated in a subtracter 23, and a signal in accordance with its deviation is output through a proportional integrator 24. In this case, a rate of change of the above described fuel flow control signal is obtained by a differentiator 25 and subtracted as a preceding value of the second stage nozzle control from output of the proportional integrator 24 in a bumpless subtractor 26 to obtain a control signal of the second stage nozzle 13.
