Stability Analysis of Distributed Engine Control Systems Under Communication Packet Drop (Postprint)

Abstract

Currently, Full Authority Digital Engine Control (FADEC), based on a centralized architecture framework is being widely used for gas turbine engine control. However, current FADEC is not able to meet the increased burden imposed by the advanced intelligent propulsion system concepts. This has necessitated development of the Distributed Engine Control system (DEC). FADEC based on Distributed Control Systems (DCS) offers modularity, improved control systems prognostics and fault tolerance along with reducing the impact of hardware obsolescence. Some of the challenges to be dealt with are selection of communication architecture, high temperature electronics and logical functional partitioning of centralized controller.
