Abstract

An apparatus for controlling a gas turbine engine. A control device is provided for controlling the energy conversion function of the engine. Adjustments of the control device are obtained by comparing an actual value of a condition of the engine with a demand value of the engine condition to produce an error between the actual and demand values and calculating a value corresponding to a setting of the control device to reduce the error to zero. A surge detector generates a surge detection signal when engine surge intensity exceeds a reference level. The engine condition demand value is modified based upon the surge detection signal to suppress the engine surge.
