Voting Software for Fault-Tolerant Aircraft Flight Control Systems

M. Bass, Julian; J. Fleming, Peter

Abstract

An intelligent and robust voting service is proposed. The novel voting service, is capable of forming a consensus based on performance of redundant applications in the value, time and reliability domains. The voter is distributed using a hot backup approach to ensure timely recovery in the event of voter failure. Specification diversity is advocated in order to improve upon the effectiveness of design diversity. The voter is designed to be a system building block, embedded in a framework of design tools which will allow the developer to express control concepts, such as deadlines, priorities, replication and voting.
