Abstract:

Gas Turbine Engine Control is one of the most complex tasks ever attempted. Currently, a centralized architecture system, labeled, Full Authority Digital Engine Control (FADEC) is being widely used. However, new engine performance technologies started to increase the burden of FADEC. This has necessitated the beginning of a new phase of engine control development, Distributed Engine Control system (DEC). The advantages of DEC such as modularity, maintenance management, and fault detection have been well established in the engine control community. One of the major challenges in implementation of DEC is selection of communication architecture and functional partitioning of centralized controller. In this research proposal, IFOS and Ohio State University propose a methodology that improves the stability and performance of the overall propulsion system under various communication constraints. In this direction, we propose initially to make use of off-the-shelf network architecture. In Phase I, we address the issues of packet dropouts, time delay and bandwidth constraints in the Networked Control Systems (NCS) and their impact on stability and performance of turbine engine. We propose a decentralized framework consisting of a two level controller. Using this approach, improved encoders and decoders will be designed to maintain system stability under these communication constraints.
