An improved thrust control system is provided for controlling thrust output of a gas turbine engine in a manner which automatically compensates for engine deterioration and corresponding changes in engine performance. The system is further adapted to control the thrust output with at least a pair of thrust-indicating parameters, such as engine speed and temperature.

An improved thrust control system for controlling thrust output of a gas turbine engine over its operational life comprising: first means for determining a first error signal indicative of any deviation of a first thrust-indicating engine operating parameter from a first reference value; second means for determining a second error signal indicative of any deviation of a second thrust-indicating engine operating parameter from a second reference value; third means for scheduling at least one trim signal proportional to both any deviation in magnitude between said first and second error signals, and any deviation in magnitude between observed thrust outputs of actual operating engines and the thrust outputs of a nominal engine, and effective for compensating for any deviation in thrust output of said engine from the thrust output of said nominal engine; and fourth means for combining said first and second error signals and said at least one trim signal and generating a thrust parameter error signal for controlling the thrust output of said engine whereby a substantially fixed relationship between the thrust output and the demanded thrust level over the operational life of the engine is maintained.
