Asynchronous Comparison Monitoring of Digital Flight Control Systems.

Abstract

A method of formulating a state-space model for the analysis of redundant-channel digital flight control systems (DFCS) is described. This mathematical representation is used to determine the effects of asynchronous digital processor operations on a system such as the DFCS for the Digital Avionics Information System (DAIS) which employs comparison monitoring and voting techniques. The report briefly discussed the evolution of digital flight control systems and the motivation for DFCS comparison monitoring. A procedure is presented for performing a covariance analysis to determine the steady-state values of inherent errors.
