“…Honeywell SAFEbus is used in the Boeing 777 Airplane Information Management System, Time Triggered Protocol-C (TTP/C) of TTA is used in the environmental control systems in the Boeing 787 Dreamliner as well as the cabin pressure control systems in the Airbus 380, and IEEE 1394b is under development for use in the Joint Strike Fighter. Out of these architectures, TTP/C has clear advantages over the others [10][11][12]. Some of the requirements of communication architecture for DCS are that it should support fault detection, isolation, and recovery and health monitoring; be highly modular, with high reliability; be easy to maintain; and, finally, have a low overall cost.…”

In this paper, we address the issue of the stability of distributed engine control systems under communication constraints and, in particular, for packet dropouts. We propose a control design procedure, labeled decentralized distributed full-authority digital engine control and based on a two-level decentralized control framework. We show that the packet dropping margin, which is a measure of stability robustness under packet dropouts, is largely dependent on the closed-loop controller structure and that, in particular, a block-diagonal structure is more desirable. Thus, we design a controller in a decentralized framework to improve the packet dropping margin. The effect of different mathematical partitioning on the packet dropping margin is studied. The proposed methodology is applied to an F100 gas turbine engine model, which clearly demonstrates the usefulness of decentralization in improving the stability of distributed control under packet dropouts.Nomenclature K 2 = spectral condition number of a matrix = max , where are eigenvalues with a positive real part = independent and identically distributed Bernoulli random process = spectral radius of a matrix = Kronecker product k k 2 = spectral norm of a matrix # = Moore-Penrose inverse of a matrix
