Apparatus and method for setting, controlling, and maintaining a given turbine inlet temperature in a gas-driven turbine and AC generator driven thereby having the generator output connected to a fixed frequency AC infinite bus. The method comprises providing electric signals proportional to generator rotational speed, turbine inlet temperature, and generator output power respectively. These three signals are processed and combined with two independent reference electric signals, representing preset desired values of rotational speed and turbine inlet temperature, to provide an output which, when applied to an electrically actuated fuel flow control means, will maintain a constant given turbine inlet temperature. The apparatus comprises means summing the turbine inlet temperature signal with a reference signal representing a preset desired temperature to provide a first output, means summing this first output with the rotational speed signal, a reference signal representing a preset desired rotational speed and the generator output power signal to provide a second output which, when connected to an electrically actuated fuel flow controller, will maintain a constant given turbine inlet temperature.
