ABSTRACT:
A control circuit for controlling output speed of a gas turbine engine through comparison between a signal representative of an actually detected output speed of the engine and a signal representative of a desired engine output speed, wherein the rate of increase of the latter signal is limited in accordance with a predetermined schedule depending upon a detected temperature of the engine and a predetermined engine temperature which varies with a preselected operating condition such as the detected output speed of the engine. The control circuit is characterized in that the same is at all times maintained as a closed-loop system although switching means is provided in the circuit.
