Abstract

The Advancement and reliability of the electromechanical system will directly affects the performance of the aircraft, since it is an important part of the aircraft systems. With the sharply increasing of the mount of date and the integration degree of electromechanical system, It is necessary to develop a distributed dual-redundancy electromechanical system which have characteristics of high-speed avionics bus, the ability to detect and reconstruct malfunction. This paper makes a research on the design of distributed dual-redundancy electromechanical system which uses the fault-tolerant technology, system reconfiguration technology and high-speed avionics bus technology, and the composition of the system, working principle, fault tolerance and reconfiguration mechanism, as well as exception handling are mainly discussed. At present, this technology has been successfully used in certain key research projects in our country.
