Abstract: An engine auto throttle control system is disclosed wherein the stability of the high gain control loop is provided by means of complemented EPR feedback. Furthermore, the multi-engine auto throttle control system of this invention generates a stable engine thrust trim command by means of a voter mechanism coupled to the respective engines EPR signals for providing a unique commanded EPR signal and by means of EPR error feedback means coupled to the commanded EPR signal for providing respective actuator signals for each of the respective engine throttle controls for trimming the engines to the same EPR value. In addition, engine overboost protection is provided to each engine individually such that all engines are controlled to a reference maximum limit.
