In one form of the invention, means are provided for sensing changes in electrical power demanded from an electrical generator driven by a gas turbine engine. In response, other means change the rate of fuel and air delivery to the engine in proportion to the demand changes and keep the combustor fuel-air ratio substantially constant.

Apparatus for controlling a gas turbine engine having a gas generator stage for supplying exhaust gases to a power turbine stage which drives an electrical generator, the gas generator stage having variable stators, comprising: (a) sensing means for sensing the frequency of the power produced by the electrical generator and for producing a frequency signal indicative thereof; (b) control means which receives the frequency signal and which, in response, modulates both the fuel supplied to the engine and the variable stators in the engine to maintain combustor fuel-air ratio substantially constant for (i) maintaining gas generator speed substantially constant, and (ii) maintaining electrical generator speed substantially constant.
